They actually did a news story on "wiggas", ten or more years ago. It's enough to make you die laughing.
Most of the young people who fit that profile didn't come from inner cities, but grew up in affluent suburbs, came from well-to-do families, but still felt the need to act like they were raised in the ghetto.
(Cue Cartman) "...And another baby born in the ghet-to" (sings "In the ghet-to!") 8)
On the other side of the coin, the Wayans brothers had a fantastic skit on "In Living Color" featuring "The Brothers Brothers" (spoof of the Smothers Brothers). Two black guys stripped of all street cred, acting so lily-white, it's as funny as the wiggas in reverse.
If they tried pulling that off today, the Wayans would probably be condemned for being "Uncle Toms". I wonder how the wiggas would be branded by the PC Police.
