de1337 

When something that used to be underground and/or 1337 goes mainstream.

Only the real origional fans feel that the band (or whatever) has been de1337ed. Everyone else pretends that they were the origional fans and that the band (or whatever) is still underground and that they are so badass for knowing about it.
