While trying to perform the act of surprise sex only to discover that you are extremely intoxicated, having "whiskey dick", and therefore disappointing the suprisee and shaming the surpriser.
MO: "So Tara what did you last night?"

TARA: "Neal, this guy I met at the bar last night, tried to surprise sex me after I brought him home, but he drank so much he couldn't get it up."

SHANNON: "Woaah, that was a major case of Whiskey Dick Surprise Sex!"
