Originated from Black youth in Washington DC.
1. Original meaning was "cant dress well" or "fashion misfit"
2. Now the word has a more general use meaning "person", as how Whites use "Dude"
1. That bama wearing a coat in the summer
2. Tell bama to meet me at the store.
Now it's more general and just means something funny-looking, unsophisticated or country as hell.
