Boston Watchman

To initiate a Boston watchman, you must be in doggy style with your girl facing a window. Simultaneously slip out while your buddy slips in without your partner knowing. As your buddy keeps getting it, walk outside and wave from a distance so your girl sees you through the window.

Totally pulled a Boston Watchman on Becky last night with my virgin friend Jake.

Boston cream

A Boston cream is when an individual consumes an entire pack of Oreos the night before having sex. He then shits in his hand, and smears it on the lady's fupa In a cake decoration type way, and proceeds to give her a creampie.

My date looked like she loved doughnuts, so I gave her a Boston cream.
