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 Gronk is fucking Tom Brady’s ass but of course he’s wearing a condom because it’s safer that way. But then he’s super excited and he is about to come! He takes the condom off and spikes it super hard on the ground then comes inside Tom’s ass. Tom complains because it’s not part of his diet and the TB12 way. But those are the breaks with a Boston cream pie!
Gronk celebrated the super bowl victory by dropping a Boston cream pie inside the best QB of all time (GOAT).
