When someone is so Intoxicated and tired that they start uncontrollably bobbing their head. Giving the appearance of giving oral sex to a ghost.
Bro! Pat was so wasted last night he started blowing ghosts at the bar. He's going to wake up with ghost jiz all over his face.

When you are sitting in class and keep nodding off so that your head slides forward and then you jerk back awake so that it looks like you're giving a blow job to the invisible person in front of you.
"I saw you over there giving the ghost a blow job"
