Dude, she was fuckin' wild last night, she started liking me everywhere and started to go down but she was so drunk that she gave me navalingus instead.
May involve inserting the tongue into the nostrils or licking the surrounding area.
Person #1: So I got this girl back to my place, and she stuck her fuckin' tongue up my nose!
Person #2: She gave you nasalingus?! What the fuck did you do?
Person #1: I gave her an angry dragon and a raspberry danish to think about.
You remember Friday night when Gary was going down on that chick and passed out half-way through? A clear cut case of narcolingus if I've ever seen one.
