What Urban dictionary should be renamed to, as all the nerds seem to post stuff noone actually says in real life, in urban environments and it gets accepted.

Guy 1 - Hey have you been on urban dictionary today. Some nerd defined leetspeak.

Guy 2 - Yeah. Since when when do you hear any cool guy that knows the lingo say 1337 in public?

Guy 1 - I know. They should make a Nerddictionary or something...
