A person of Italian descent who acts extremely white and/or even worse; redneck. These people are not at all proud to be descended from a Latin people and in fact wish they could be of full Nordic, Germanic, or Anglo Saxon descent. The vast majority of them can't even pronounce their own names.
The name of the 1980's dance often performed to hip hop / rap songs where you stand with your legs still and start to worm your upper body forward and then up and down.
note: many Italian Americans teens were severely scolded doing the "WOP" in the 1980's for participating in such a dance because the name "WOP" is also a word to negatively describe an Italian American. True story!
