southern term for an ugly woman. marmasoot's are usually found in bars and clubs looking for drunk men who are unable to see or make clear decisions.
The degree to which one is a marmasoot is based on poor looks, being over weight and poorly dressed.
I hope I don't get to drunk tonight and hook up with a marmasoot.
Look at that fat, ugly chick wearing spandex, what a marmasoot. BIG TIME!
