BTW whites ought to stop calling boys "Troy" or "Tracy" for the same reason. "Trey" is unforgivable on a birth certificate, but is permissible as a nickname, only if the child is a "three-sticker"=child given the same name as his father AND grandfather...
The last few Treys I've seen have been black kids, and it's been short for Deontrey, Shontray, or similar names.
