annoying ass people at dances, all they do is fist pump and get in other peoples way when they are trying to get their twerk on. they all also called anti-twerkers. sometimes try to start a train when other people are too busy twerking.
Jason: How was the dance yesterday?
Dennis: It was horrible, fist pumpers were blocking my girl and me
Jason: That sucks. Well I was throwing my hands in the air and grinding on a girl while some guy was trying grind on me
Dennis: Dude, I think you were the fist pumper
Jason:..........
