Brian: Sure, dude.
Alex: Go ahead I just finished banging Ashley.

Get the Boston Creme Pie mug.
When you and a girl are going at at in whatever gets you aroused, before you "finish" with her, you take a dump on her vagina and nut all over it.

Get the Boston Creme Pie mug.
When an "Irish looking" woman performs oral sex on a man until he ejaculates a huge load all over her pale, freckled face.
Kevin once told me a story about this chick (whose name rhymes with pita) that used to blow him. Even though he wasn't into redheads, he couldn't resist the temptation of giving her a hot, sticky boston creme pie.
