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
"whoa, look at that girl over there....she's such a SHMUT"
