A derogetory term for someone from
Wales. Actually, the derivation of this word is as follows (from the racial slur database): "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)."
