Mustase 

The enzyme used to break down the Must molecule into its smaller musty parts.

Doctor: I'm sorry Yash, but you have been diagnosed with terminal Must. The only cure is to take Mustase enzymes to cure the must.

Yash: Oh no, but I want to be musty, I will take the L and die a musty death.

Mustaeen 

The literal definition of an asshole. Backstabs friends, takes hundreds of photos of them without their permission, and acts like he's the best at everything but everyone knows hes not. He will always talk about you with others, and share pictures despite the fact that the victim knows about it. Usually this person will make someone look bad so he seems cooler than them. He also likes to lure in girls to play minecraft so he can get coochie.

Man, that guy is such a Mustaeen, I wouldn't wanna be his friend.
