I agree that it's pathetic on how over hyped OG usernames are. To the extent that they're willing to pay money for it!

I think the term "OG" has been taken to a different level. These gamertags/usernames are more like "Simple." To me, and "OG" GT/username is something that, as someone has already said, represents you. Original should be something that YOU think is original. Mine is AvengedCH. Avenged is the first part of my favorite band's name. CH is my initials. To me, that's original because no one else can claim to be AvengedCH and it have the exact same meaning. This is opinionated.
