As a girl is blowing you and just as you are ready to cum, you grab the back of her head and shove her mouth all the way down your cock as you cum. If your timing is right, you will cause her gag reflex to trigger and your cum will shoot out of her nose, much like a kid that can shoot milk out of his/her nose.
Cum burns coming out of someones nose, much like fire would coming out of a dragons. Hence the name ... Angry Dragon.
She'll never call me again after I gave her the Angry Dragon!
I would pay that slut a lot of money if I could give her an Angry Dragon.
