The sudden and obvious onset of marijuana induced paranoia in a very public setting.

So named for the subject's tendency to adopt all the nervous and fidgety mannerisms of the stereotypical "socially awkward white guy" irrespective of one's actual race.

Dude Jon is totally flipping a whitey in the middle of Tiffany & Co. Get him the fuck out of here before they call SWAT.
