The act of ejaculating inside a MIT undergraduate whilst saying "F**k You, Oh yeah" in a concentrated, pronounced Bostonian accent. Duration varies between six seconds to a full two minutes. In order to be accurate, one must wear one of the following while committing this act: A Celtics jersey, New England Patriots Jersey, or red socks. After ejaculation the partners must deposit the semen into a cup of New England clam chowder - only New England - and thereafter consume it with Irish beer.
Goodness fucking gracious do you smell that good-ass clam chowder? A couple must've gave each other a Boston Creampie!

a three way homosexual act involving at least one filthy irish guy who takes the cum of the first gentleman(often black) up his ass to have the 2nd one(often italian) eat it out of the irish guy's asshole
a black guy, and a filthy Irishman walk into an Italian restaurant and yelled "which one of you guinea bastards wants a boston cream pie for desert?", as he bent the irish guy over the bar and fucked him in the ass.

When a woman takes a dump and doesn't wipe, and then her boyfriend fucks her and cums inside her unwiped, poop-covered asshole.
My girlfriend asked if we could do something different tonight, so I waited for her to take her nightly dump and I gave her a Boston Creampie
