...as in, "I never met a YART I didn't like."

Which illustrates the issue quite nicely. Should we articleulate alert: neologism YART or not? It's an acronym, a phrase rather than a noun. It contains its own article; isn't calling it "a YART" like talking of "the hoi polloi"?

Is it appropriate for a bunch of word fans to be saying "This is a YART" or "Maybe it's just another YART but..."?
