Angry Dragon

Causing semen to come out of the nose of the person who is performing fellatio.

From Dick Broom:  To perform this maneuver when the person getting the blow job cums into their partner’s mouth, they give them a good karate chop/slap to the throat making the person choke on the cum and shoot it out their nose. The angry part comes from them being pretty pissed off that you just hit them after they blew you.
