Urban Underworld 

(aka, SoSlang.com)

A secret URBAN-D society that is engaged in and organized for the purposes of crime and vice against the Urban Dictionary. They appear to have successfully cloned UrbanDictionary.com and all definitions as late as 2012.

If you ever accidentally delete a word on Urban Dictionary and want to find it, just head on down to the Urban Underworld and tell them Danger Doll sent ya, (Oh wait, there's conveniently no way to contact anyone on that website and no 'remove' feature.)

Underworld 

Underworld racing is an illegal form of street racing that takes place in urban areas. It is typically organized by underground racing crews and involves modified vehicles competing in short races on city streets. Races are often dangerous due to the lack of safety regulations and can involve high speeds, close contact between cars, and other illegal activities.

The underworld is believed to be the inferno to the collective.
