A man who farts up his nose while auto-fellating himself usually for sexual pleasure, but sometimes by accident

The act of taking a pull from a vaporizer tank without use of a protective drip tip and/or top cap.

Basically putting the lips on hot metal tube and inhaling vapor.
Dude...I'm so high, I almost started mufflering my vape RDA without the top cap. My lips would have been burnt and blistered like a herpes outbreak.
