Mine dates to a cleric character of mine from an AD&D Greyhawk campaign circa 1986; Hexiir of Keoland, priest of Wee Jas, god of the dead.
So, unless you were hanging around the poorly lit and Mountain Dew tacky gaming tables at the back of Jelly's in Aiea, HI 27ish years ago I'm pretty sure the name was original when I coined it.
Ah...nostalgia. Other fond memories from that era include:
Dumping $20 worth of quarters into Guantlet II (and still getting nowhere near the end). "Teenager needs food...badly..."
Aliens the movie. A staple for any true-blooded roleplayer. (Yes, even the fantasy guys.)
The first superbowl I ever watched...in which my beloved Patriots got their asses handed to them by the Bears. Jim McMahon and Walter Payton were playing for Chicago...and I am chagrined to say I can't remember even one Patriot.
Good times...
