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!

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

The sex move is just a normal cream pie but you’re wearing a Red Sox jersey, holding a cup of iced dunks and you have to yell out “wicked smaht” upon climax. The dunks is optional. You can switch it out with a Sam Adams.
Patrick: Hey Sean! Gave my old lady a wicked Boston Creampie the otha' day!
Sean: You guys went to Faneuil Hall?
Patrick: Nah.
