Popularized by Neopets user Elliot of the Evil Things and Monster Sightings (EMS) board, "ohemgee" has come to nearly replace the usual "omg". Whether or not the term would have reached such high public knowledge if someone such as Elliot had not coined it is still under debate.
Elliot first gained recognition on EMS by becoming friendly with the infamous Judas, a troll of high status on the board. Elliot is a cheerful, flirty, and outgoing individual, but his past is troubled and sometimes he just needs to "freak out" and will become surprisingly bitter and sarcastic.
We're wondering why he doesn't just become a goddam emo kid already.
Bill: OHEMGEE today I saw watchmen and I was liek :O:O:O!!!
Bob: Yeah, ohemgee that WAS good!
