A young Armenian male residing in the U.S. (mainly in the L.A./Glendale, CA area) who is usually defined by his oily hair, over usage of cologne, cigarette breath, facial hair of some sort, excessive jewelry, jump suit, and a Beemer. These traits are similar to the North East U. S. "guido," who is usually of Italian descent. Hence the word: GUID + IAN, where "guid" is derived from "guido." The "ian" ending comes from the suffix of almost all Armenian last names.
This Beemer full of guidians barely ran me over when I crossed Glendale Ave!
