To Must, To be musty;
To emit a horrific odor. To smell extremely bad. To smell like armpits, boiled ass, chopped onions and fried corn simultaneously;
To smell like horse sex mixed with shrimp, rabbit urine and senior citizen shit.
Person 1: WTF is that damn smell?
Person 2: Oh sh.. PISS!
Person 1: Seriously what stinks damn?
Person 2: It's that musty ass indian dude over there, smellin' like curry and armpits n shit.
