I don't know but I find that kinda stuff interesting.... if anyone has some info on this type of thing I'd like to check it out....
my mom took some "community accademy" thing through the Police Department and they gave her a book full of info... it had a section on gangs and one of the terms they said folks used for fighting was "bumping uglies" I have yet to hear someone use this term for fighting.... so thanks for reading my rant
