Boston Creampie 

the act of ejaculating inside the vagina or anus while shouting "LET'S GO RED SOX" and slapping the penis 1-2-123 on whichever surface one ejaculated inside, as if you were at a baseball game

So I brought home this girl last night, and i found out she was a Yankees fan, so when i finished, i gave her a Boston Creampie.

The Boston Creampie occurs when, seconds prior to ejaculation, one removes the phallus and ejaculates onto the abdomen of another. One must then urinate onto the abdomen and/or upper torso of said ejaculate catcher in the shape of the letter "B". This is only worthwhile if the receiver is a fan of the New York Yankees Baseball club.

That cumdumpster I fucked last night told me she is a Yankees fan, so I gave her the Boston Creampie to show her the error of her ways.

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

Boston Creampie 

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!
