when some chick is giving you a bj and you push her head right down onto your dick just as you shoot, and your dick is so far in her mouth the spunk comes out of her nose.
"Dude, the other day this girl I know sneezed, and some white stuff came out. She must have been dragonned!"
"Man, this chick was so ungrateful when I dragonned her, she hocked it back up and spat it in my eye!"
