THe only time i come across 'white off' type stuff is when you sometimes encounters WASPs (white anglo saxon protestants for the deaf dumb and blind) who truly think they are above everything.
I have some WASPs in the family and they do this jokingly and we exchange ball busting between WASP and italian.
They'll give us the old greaseball, half nigger shit, so we usually always brag on our tans (cuz they are the palest creatures on earth, they will tell you this tho) and how London was a Roman trading outpost.
nobody gets sensitive tho. Alot of whites do this amongst ourselves because we are very different from eachother yet, we band together to form a cohesive white unit, generically in the US.
its quite an eclectic club.
Look eye, always look eye.
