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!

Get the Boston Angelmug. A “Boston coffee shop” is a sexual act where you toss donuts onto the erect penis of a professional athlete until you get one on. You get 6 tries. If you get one, you cuck him. If you miss all 6, he cucks you.
I can't wait to see if Tingus Pingus is at the store again today. If he's there I may ask him to try a Boston coffee shop.

Get the Boston Coffee Shopmug. Getting a bunch of British chics in a tub of dirty water, preferably after performing a "Boston Cream Pie". Then tea-bagging them with your American balls, one after the other after not showering for a week. All while drinking a Sam Adams and pouring Earl Grey on their little British heads.
