"The Must" or being "Musty" is a feeling one has after getting really high. It's a feeling one may experience when they feel as if they are watching them selves in third person while still looking through their own eyes.

Bro 1: "man that is exactly what it feels like!"
Bro 2: "yeah man you got The Must!"
