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.

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.

I knew she was a true Red Sox fan when she asked for a Boston Creampie during the seventh inning stretch.
