Brewer's Droop 

Also see beerdick. The condition that occurs when a gentleman over-indulges on alcoholic beverages and can no longer maintain an erection.

Probably has some historical basis, or something.

LOL, Carter was totally gonna bone Sharon in the ringpiece, at least until he got the Brewer's Droop. They both went home disappointed.
