sleep dicking 

The attempted misplacement of the penis while the 'unfortunate target' of the 'slip of the sausage' dreams of an uncomfortable anal experience. The unfortunate target generally wakes up complaining about having a sore bottom, to which the 'sleep dicker' pretends he has no idea.

"Bud! My ass hurts! You weren't sleep dicking were you?" "Huh? You must've rolled over on the flashlight!"
