Get the Boston Splats mug.
A sexual act the involves the game of hockey. It is done when a naked male plugs into the butthole of a female, she than inserts a hockey stick into her vagina. This act can only be successfully done when they skate in tandem and score a goal. After the goal, the male than ejaculates and in celebration thrusts the female into the boards. Once the vagina extracting hockey stick hits the boards it than flings the female into the sky and creates a bloody bug splat into the plexy glass.
Damn Sarah looks pissed, did someone give her a Boston Bug Splat at last nights game?
