JFK'ing 

When you are so tired your head falls violently rearward, as if you were just shot in the head.

"Damn Jeff, are you allright?"
"Yeah man, I'm so tired, just keep JFK'ing"

Sucking a Ghost dick 

At a state of utter fatigue, when your neck becomes rubber and your head bobs forward as you try and stay awake. Essentially, sucking a ghost dick.

"Damn, Jack totally got a video of me sucking a ghost dick last night."
