Salvidrim has become a net-wide phenom over the last couple of years. It is a username appearing on thousands of sites, most of them gaming-related, but some are not. It is believed that a single individual is behind all the usernames, but the rumour that he is ubiquitous has been disproved.
MMO-Player1: Hey, there's a guy named Salvidrim over there! I think I saw that name on another game...
MMO-Player2: Of course you have, he's playing more Internet Games than than Moldavia has citizens.
