the sexual act of a man, during intercourse, taking a sumptuous dump on his partner's mammary area (dude shits on chick's boobies.)
chick: ... and then the guy shat on my breasticles!

friend: oh damn, i got that the other day!

dane cook: it's a boopoob, a new trend i started. it's sweeping, no, swiffering the nation!!
