A group of Urban Dictionary editors who only publish their entries and there friends, thus making it much harder to 'Define your world' if you are not in their elite clan.
Probably a group of 10-14 year olds who think they are cool because they can suppress others opinions.

When you eat dirt for the first time and leave your family to build a shack in the woods

dumbasses who spend all their time looking up stupid shit on this website and reviewing other people's slang terms to make sure they are not in violation of some sort of rule.

A man (mostly men) that refuse to accept good sound urban dictionary definitions without valid reason and also without any empathy for how the submitter must feel (rejection after rejection).
