Someone of middle class origin who seeks to (do their part) by working in the education sector in the most impoverished urban areas. Due to their own personal irresponsibility they often fail to maintain this employment and have to return to their middle class environment. The experience often becomes "noble work" fodder on the ghetto raiders resume when they return to the job market.
The boss should probably hire Willy as the new supervisor...He's been here for years...but I imagine they'll bring in another ghetto raider who will be gone in a year.
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".
Two examples of things which are Ghettoridiculous
In a grocery store: (loud as you can)Shanikwa, you betta sit yo ass in that cart fo i beat yo mutha f**kin ass!!
