Found this while googling for definitions to some hax0r terms.

http://www.urbandictionary.com/

Design motif looks identical to dictionary.com - though I get a sneaking
suspicion they ain't part of that site...

like other online slang lexicons, the content here is at least partially
user-driven (Add Your Own Word link).

(c) date makes it look like this one's been around in some form since
1999....
