To shmut is to do facial and hand gestures to express a sense of bragging. Very fast motions, with sound effects.

lil mad is like big mad but the opposite, you mad but not mad to the extent of pullin somthin

A lot like "shmea", but it is a bit like a "shmea-ish mutt"

So i would call my dog (who is a mutt) a shmut, because it's a cooler word

or it could be like slut. so call someone you think is a slut a shmut, and they will have no idea what the hell you are talking about

A dirty rat asshole whom you dislike strongly to a puddle of shit on a trash bag
