A stank ass person who is rude, uncouth and pure trash. They’re such a bad person their soul emits the smell of unwiped asshole, penis crust and boiled ass.
Damn, people act like pure MUSTIES during the holidays.
Have you met that dumb ass Eddie? He’s a MUSTY ass bitch.
The keyboardist of the band Dimmu Borgir. His real name is Øyvind Johan Mustaparta. He's incredibly sexy, talented and intelligent. He also looks like a young Shagrath.
