The racial slur of the day is Taffy.

It is used to refer to Welsh.

Deep lore: The Taff is the name of the river that runs through Cardiff, the capital of Wales. Also from a poem that starts: "Taffy was a Welshman, Taffy was a thief...." Another explanation is that Taffy is based on an English pronuciation of the common Welsh first name, "Daffyd" (David).
