My ex stepmother constantly bragged about being a cheerleader in high school and winning a beauty walk (in a town of like 500 people). She was still bragging about these the last time I saw her. She was in her mid 40s. -jewelsforfools

"It doesn't get better once you grow up" I told a sub teacher at my school that people told me this all the time and she told me the only people that say that are the ones that peaked in high school. I miss her every day. -HoudaRat

Talking about high school in every conversation and gossips like a high schooler. -southwest_southwest

Anyone who bullies other adults as if they were still in high school. -pkeit32

I had a conversation in a bar with a drinking buddy years ago. The guy kept going on about "the one that got away." How perfect she was and their chemistry together, how natural it was, how he hasn't felt that way about any girl since, yadda yadda. He was feeling pretty sorry for himself and uninterested in meeting anyone else because they could never compare. When I asked how long ago it was that she moved away, he said "8th grade." LMFAO. -dickbaggery

They still brag about their High School GPA. -SinisterYear

I used to work with a guy, we used to call him roid rage. He was very muscular, very masculine, and let everybody know both those things about him constantly. One day I'm sitting next to him in the break room and he's talking to me, unprompted as always, about how he went to attend an award ceremony for his son who won something regarding his football performance. I said "Well that was nice of you to go and support him."

"Nice?" He said. "It was f*cking sad man. That used to be me. Now I'm the old guy in the room who has to watch someone else win something I should have had" and all I could think was what a loser, you can't just be happy your son won this award and be proud of him. You have to make it about you. -gamercboy5

"Hey girl hey! Do you wanna be your own boss babe while working from home?!" and its just a pyramid scheme. -Tyler_origami94

Regularly reposting the same picture of the one notable moment that they had in high school. -MissingDarts

Almost 10 years after high school a guy asked me if one of my friends "was popular in high school". -satirevaitneics
