Sometimes I think that people making lists on Wikipedia are tempted to invent a few of their own additions...

From http://en.wikipedia.org/wiki/List_of_ethnic_slurs:

ABCDEFGHIJKLMNOPQRSTUVWXYZ (Subcontinentals in U.S.) "American Born Confused Desi Emigrated From Gujarat Housed In Jersey, Keeping Lots of Motels, Named Omkarnath Patel, Quickly Reached Success Through Underhanded Vicious Ways, Xenophobic Yet Zealous": Extended version of ABCD used for American-born Indians who are confused about their culture, implying greater racial and cultural disparagement.

Ahhh-Jew (U.S.) Indicating that a Jew is present with a false sneeze

Americans Americunt/A Merry Cunt (UK) an American tourist

...and those are just the A's.
