UrbanDictionary Nerd

One who spends large portions of his or her time on the site Urban Dictionary aimlessly typing in letters to see what weird definitions others have written.
In addition, this group of people occasionally write their own definitions in an attempt to be funny.

But worst of all, UrbanDictionary Nerds are simply filthy hypocrites.

If you are reading this, you're probably an UrbanDictionary Nerd.
