I thought of one today. It's not really a gym pet peeve, it's an internet pet peeve because I've never seen it actually happen but I have seen people bragging about it, usually on the SS forums (lol everyone there is a pet peeve because they're all *******s). When people ask for a spot, and the spotter does it wrong, and they shout at the spotter. Yeah, you asked a stranger for a favour and they took time out of their day to do it just because most strangers are nice people BUT THAT SELFISH MOTHER****ER TOUCHED THE BAR TOO EARLY OMG MY GAINS ARE RUINED SO I AVERTED THE CRISIS BY CUSSING HIM OUT IN FRONT OF EVERYONE. Sure you did. But since they think it's cool to go on the internet and brag about being a total sociopath it's possible that it actually happened.
