You cum in a girls mouth and then clamp her mouth shut. Then you tell her you have an STD. She freaks and tries to spit it out, but with her mouth closed still by you all the cum comes out her nose. That's an alaskan snow dragon son.
Giselle: This morning i was in class and cum started dripping out my nose!!!
Giselle: It's probably cuz Ian gave me an alaskan snow dragon last night! =)
