mercantile pretzel 

A sexual position with two men and a woman. One man is fucking the woman while being fucked in the ass. Named after a popular GLBT bar in Sacramento called the Mercantile Saloon (known for pouring heavily and not charging much) where the idea was conceptualized.

Treighton is the middle in a mercantile pretzel with his girlfriend and the random guy from the gay bar.
