Being a teacher can often be a frustrating job. From loud kids to piles of F papers, it's never ending. Well, these teachers just snapped...

“Within 5 years that kid will probably kill himself in a car wreck.” A year later, he did. Source

You Can’t Take That One Back

My grandpa died literally the day before my final university exam, so I applied for special consideration immediately. One of my university’s staff members, who apparently had some sort of chip on her shoulder, was deliberately delaying my application by continually “misplacing” my paperwork. After two months of jumping through this woman’s hoops (all other applications were approved or declined within 1-2 weeks) I emailed directly to her boss to complain about her.
Not long after that I received an email from the woman, who called me, and I quote, a “queue jumping, daddy loving trollop”. Half an hour later I received two more emails, one from her and one from her boss, apologizing profusely. The boss then informed me that my special consideration was approved, and that the woman had been fired. Source
The Poster Child

I worked at a Catholic school. One I overheard a teacher say, “I know we’re against birth control, but that kid is a poster child for using protection.” Source
Cruel Punishment

I heard a story about a teacher that had a miscarriage. When she came back from rest she said to a student:
“You’re the reason why I lost my child” Source
A Questionable Gesture

I taught in Japan for a bit. I was kind of lucky because I got to start in the middle of the year, as a result of my mid year application for the job (usually school starts in April but I applied in July, started in August).
The reason I got to start in the middle of the year was the guy teaching at that school before me was fired for inappropriately harassing a student.
This was at a middle school. That guy was in his late 20s and he was hitting on a 15yo girl. She was wearing a kimono at a festival and he asked her if she was wearing anything underneath it. He had a history of creepiness towards the girls, so this was the last straw.
So now I’m working there and getting along great with the staff because I’m not a creep.
One day I’m getting a ride somewhere with the Vice-Pricinpal and we pass some high school kids on their bikes. He leaned over in the car and nudged my arm and gestured to some of the kids. He said, “Hey, hmm? High school girls!”
It was uncomfortable for the rest of the ride. I think he was just testing me to make sure I wasn’t like the previous guy, but I’m not entirely sure Source
If Words Could Kill

My junior year a teacher had a miscarriage. When she came back she was a bit mad at the class for a bunch of kids acting like jerks and yelled quite a bit. A student got up and said something to the effect of, “Guess it’s good thing you had a miscarriage.” She broke down and cried. One of the other teachers came and got her. For about 15 to 20 minutes there was total silence. Then the Vice Principal came in with a totally red face. Kid tried to say she deserved it and fought back when he tried to grab him. The Vice Principal punched him. In the face. Hard. That kid stopped fighting.
Total silence for the rest of the hour. Vice Principal never got in trouble. Parents actually approved of their kid being suspended. Source
The Music Maker

I can confirm. I am a band director. We have our breaking points. I once told a clarinet player who dropped her clarinet on the floor that’s the best sound she made all year. I will not reveal what is said by others. Source
Silent But Deadly

My orchestra instructor in middle school was constantly flipping out. He told first violin to shove his bow up his rear. He told another kid to go sit in the trashcan when he was acting up. The kid took it as an invitation and did it. He also told me that my parents were wasting their money on private lessons because my cello sounded like a donkey being murdered. He was our favorite teacher, BY FAR. We loved him so much. At the end of the year he gave our parents a cd of our performance and said, “Play it with the stereo on silent.” He was the best Source
Someone Loves Their Job

I went to the high school my mom taught at. Teachers were at my house ALL THE TIME. They never held back anything, and so it is nearly impossible to distill it to a single thing that one of them said.
But here are a few that stand out:
“I just hate [future valedictorian], but I’m not going to be the one who gives him an A- or his mom will throw a fit. It’s not worth the hassle.”
“That freaking kid has no sense of reality. Once his daddy’s money stops flowing, he’s going to be in prison. I can’t wait to visit him there.”
(Regarding two attractive twin brothers a year behind me) “Which one is hotter? I’d go for ’em both – at the same time!”
“I would kill that little kid if I could get away with it” Source
Oh Wow…

My senior year of high school I took a freshman class that was required to graduate. My teacher turned to me once when all of the freshman were being loud and said, “This is why they don’t let teachers have guns.”
This same teacher was arrested the next semester for taping a camera under the sink of one of the handicap bathrooms.
Another teacher was arrested that same semester for having taken pictures with hidden cameras under desks, and an ipad which he would slide out from under his desk when students would go up to talk to him. They were stored on his school computer and discovered by a student. His reasoning for doing this was something along the lines of “It started as an accident, and then became a challenge to see how long I could do it” Source
Same Boat

Director in theater department consistently talked about strangling some of the spoiled brats they had to deal with, I was on the same boat Source
Plot Twist

I heard a lot of creepy comments about female students. Some were subtle and some less subtle. But the worst one was actually from a female teacher talking about a male student.
Paraphrasing- “When he wears those tight jeans, I just want to give him a spank, you know?” She used to buy him stuff all the time and pay him a lot of attention. People thought it was strange. *But it was okay because she was also his aunt *Source
A Military Brat

I went to military high school. My friend, a colossal screw up, was dubbed by my algebra teacher “the poster child for a 9mm retroactive abortion.”
My friend protested, so my teacher gave us an in-class assignment, issued my buddy a 35lb log, and made him run around the parade field with the log on his shoulders.
They don’t mess around in military school Source
Why I Oughta…

Taught English in Korea for a year to elementary students – was having a conversation with a teacher after he’d finished his sixth grade class and I guess he was especially frustrated that day, he wrings his hands and goes, “Oh my God, they don’t know I could break them with my bare hands if I wanted to” Source
Swears Like A Sailor

I have a colleague who swears like a sailor. It’s her first year in the profession and she’s had about six incidents where she’s sworn in front of students, accidentally letting a swear word slip out in class. That pales in comparison to the way she speaks about them out of school:
She referred to a 15 year old boy with Fetal Alcohol Syndrome as ‘looking like a mistake.’
She referred to a student’s mother as a potato dumpling.
She pointed out an Aboriginal student by saying, “The trashbag next to the white kid.”
And she called our principal an ‘unapproachable autistic d-bag.’ Source
As Bland As A Shoe

Not a teacher but–when I was in elementary school my friend overheard my math teacher telling another teacher that talking to me was like talking to a shoe. Source
What Chemistry

Our chemistry teacher was taking a class on balancing chemical reactions. There is this couple talking, giggling and disturbing the class. Our teacher looks at them and says “You guys have a nice chemistry going. Just don’t turn these reactants into products” Source
What A Pain

I heard that some teacher at my school once literally told a student that he was a ‘nasty filthy little piece of trash’, and that he ‘should go back to the toilet he was torn out of’. That teacher was really angry, and the kid he insulted really was a brat. He got an official warning but got away unscathed. The kid was one that could handle things like it so he took it lightly. It sure left an impression though Source
What Pervs!

I used to have two math teachers. Older men, and they would send various girls to and from each other’s classes with “important messages” to give to the other teacher.
Years later I talk to one of the girls and turns out, they were sending hot girls dressed in something like a short skirt or revealing outfit for the other to check out and the notes always had something gross and raunchy on it. Source
What The…

I once commented that a kid (who was multiracial) was cute. An old lady teacher responded with, “Yeah I know, especially considering he’s one of those half and half things.” WTF? Source
I Will Smash Them

In high school I had a teacher tell me in class a few times if I don’t shut up he will take my junk and smash it with a pin hammer. He was from Odessa, Texas and sounded exactly like Hank Hill. We all loved him, so it wasn’t an issue. Source
If I Was Your Age…

A bit late to the party, but I had to chime in on this one.
High school, junior year. Most of us were around 16, some had been peaking into 17. In my APUSH class, our teacher had been making some really sexist remarks. I had only been half listening so I can’t really tell you then verbatim, but it essentially led to one of my girl classmates telling him, “If you were my age, I’d slap you so hard right now.”
Almost immediately, as if he had been waiting to say it for a long time, he nonchalantly replied back,
“If I was your age, I’d be on top of you in the back of my truck right now.”
The worst part is that he still works there. The school can’t bring itself to fire him, and he’s gotten away with so much stuff like this. Source
Parents FTW

Colleague of mine called a student a swear word and kicked him out of class. Immediately after class, the teacher called the parent and confessed and apologized. The parent forgave him and apologized for his son’s being a jerk. Source
An Unknown Naughty Word

My teacher told us that a couple years before we had her, she had purposely called a student a word that she did not know was inappropriate. She only told us that it was a 7 letter word that started with S. Naturally I dropped everything, stopped paying attention, and started racking my brain for every naught word I knew until 5 minutes after the conversation had ended I screamed “SCROTUM” in the middle of algebra.
Teacher did not confirm nor deny, which means she confirmed. Source
Now That’s Uncalled For

There was a kid in my gym class who had a speech impediment and when he wasn’t around the gym teacher would openly do offensive impressions of him in front of all of us students Source
Stupid Comments

Student here. My math teacher constantly makes “jokes” about kids in my class in regards to their race.
If you’re Asian you will be told to “stop studying Chinese characters” if you are not paying attention.
If you’re Latino he will ask questions about which community college you’re going to.
If you look European (like I do) he assumes you’re an immigrant. I’ve been told multiple times to “make sure to write your test in English” and when calling him out on that be told something along the lines of “in Poland your behavior would not be acceptable at all”.
All while keeping a stupid grin on his face. I wonder how he still has his job Source
