Any behavior generally described as ghetto. Especially when these things are done in a place where civil behavior is generally expected. Such as talking like you didn't make it past second grade, talking as loud and as obnoxious as possible, slapping and threatening your 1 & 1/2 year old kid, playing loud
unintelligible banging music while driving
down the street, beating people up and/or shooting them for the slightest reason. Beating up your sister for
sleeping with your baby's daddy that just happens to be married to your cousin. Basically behaving like slaves gone wild and calling it "acting black".
