A sexual act in which a couple is having anal sex. It starts with the male riding on his girlfriend’s back like a horse and hollering, “YEEEEE-HAAAAW!!!!” while his dick is still in her turd-filled ass. Then he whips his dick out of her butthole and drums on her buttcheeks like a set of bongos until she projectiles a massive shitload all over him and the bed.
Kyle gave his now ex-girlfriend Taylor the ol’ classic boom-boom. He pounded the living shit out of her buttcheeks so hard that she shit all over his legs and the bedsheets and now he won’t go out with that disgusting cunt anymore.
