Lol. I'll have to remember that one.
'jewish turd' is another one I've heard.
'cuntastic'
'arsewipe', 'arselicker'
Also an amusing mistranslation to american-ese, is in sign languages, the BSL for 'goodbye' translates into one of the signs for 'bitch' in ASL. I fairly frequently use ASL obscenities to broaden the range of options for flipping people off when that is called for.
