A cruel and disgusting variation on the buttshover maneuver of bullying, where jocks take a nerd victim and press his face into one jock's butt, and that jock poops on him - specifically, this variation is when the jock has explosive diarrhea on the nerd's face. Since this is hard to predict, it is usually meant to be a regular buttshover and happens by chance, so if a butt bomb does occur it is considered a moment of honor for the jock and typically brands the nerd as the permanent victim of that jock, who assumes the responsibility of bullying the nerd daily for the indefinite future.
Jock: Bro, I went to give some dork freshman a buttshover the other day and I guess I must be getting sick it ended up being a butt bomb. Nastiest thing I've ever seen.
Jock's friend: Duuuuude, that nerd is like your bitch now. He's gotta be in for a stinky year!
Jock: Fuck yeah he is. I'm gonna go find him and give him a chocolate swirly.
