I haven't heard of "Kike," but isn't "Heeb" one? Canada has taught me much.
In Arabic we don't really have any words, we just call out the ethnicity followed or preceded by a cuss. Although whenever "the invaders" or "the tyrants" is uttered it's generally a common understanding that we're talking about Zionists; not Jews (there are Arab Jews too y'know).
Hmm, I guess "chink" sounds funny. Like a chink in your chain, or onomatopoeia "kachinka chink"
