After the act of sex the man takes his used condom, twirls it in the air like a helicopter and then throws it onto his partner's body, thereby cause his "seed" to explode out like a bomb. It is traditional to yell out "SEED BOMB" as one releases to throw.
Bro 1: Dude did I hear you hooked up with Chelsea last week?
Bro 2: Hell yeah man, f****** seed bombed that sloot!
