Sleep jerking is an unfortunate chronic condition where a person will unconsciously pound one out.

This condition is derivation of 'sleep walking' and "talking in your sleep' but much more serious and in certain situations, very embarrassing.
Mark passed out after smoking too much weed at the party, whipped it out, and proceeded sleep jerking in front of everybody. It was only until people started to cheer him on when he woke up.
