The racial slur of the day is Chink.

It is used to refer to Asians.

Deep lore: Asian equivalent of "Nigger" for blacks. Two possible origins: the dictionary definition is "A narrow opening or slit", meaning a reference to their eyes. Or could also refer to the sound of someone working on a railroad, which Chinese immigrants helped build in 1800's America. Technically should only refer to Chinese, but used for all Asians.
