A white male youth from a middle class or upper middle class upbringing who wants desperately to fit into the urban gangsta lifestyle in his grammar, musical taste, clothing and attitude but who only serves to irritate everyone, including real gangstas.

Any white male age 10-25 basically.

A very annoying white male youth that desperately needs to be dropped off in Compton for a day or two and be taught a lesson.

Any white male that likes Akon.
The 7-11 was not the best choice for a late night snack that night as the parking lot was infested with crunked up yo boys listening to Akon on the car sterios of their Jetta.
