stick shaft

When a car hookup is about to go down and someone opens the car looking for someone/something else and is encountered by two naked people about to do the do.

Alex: I was just going to find Mike and I opened his car door to find Jack and Ashley about to do the nasty. I just totally got stick shafted.

Jack: Alex, you're such a stick shaft.
