Jason S. sent us this picture of a T-shirt he saw for sale in Berkeley, California. The T-shirt says:

Wingman Services: Don’t Be Sent Out On A Dangerous SOLO Mission!  Let Us BANG Her Fat Friends For You!

A “wingman” is a guy who helps his buddy get laid.  Here the suggestion is that the “wingman” will take the fall and have sex with the fat one so that his buddy can have the desirable, skinny one.  Notice also the violent language used to describe sex.
