Was he name LeRoy, by any chance?
No. There’s more than one of “THAT GUY”. LOL. Probably 60% of the people that play it.
He lived with us because I got him a summer job where I worked. He would stay up all night playing WoW and would come in without a shower and 2 hours of sleep.
It’s really funny now looking back on it, at the time it was incredibly frustrating.
