This is a variation on the more well known Angry Dragon (get head, cum, choke her on your dick, then it comes out of her nose). All you have to do, is punch a girl in the face, thus giving her a bloody nose. While blood is spewing from her face, you punch her in the stomach, causing a rapid release of air from her mouth, spraying blood everywhere and resembling a dragon breathing fire. She will be very pissed off, thus the name the 'Angry Dragon." No head is necessary to perform this, although it makes it better, because you get your dick sucked as well.

When you cum in a girls mouth and then smack her head so it comes out of the nose.
