EAST COAST IS WOPLAND TO ME AND U...
I haven't heard the expression 'wap' since I was a kid. It was derogatory back then. Has this changed? My completely bigoted grandfather had unpleasant names for everyone; wap, spic, guy, chinc, frog and so on. He was not a nice person. You are Italian, so I guess it is okay that you refer to yourself however you wish. This is like when a black person calls another black person n i g g a' and that's okay.
An aside....it is too bad that some terms are censored when they weren't used in a derogatory or hateful way. Seems rather juvenile.
