Urban Dictionary

One of the most amazing and terrifying places to visit on the interwebs
It not only defines almost any word you can think of, but it does it by real people and in the most amusing (and terrifying) of ways.

Person 1: I went on Urban Dictionary today to look up a word
Person 2: Yeah and?
Person 1: It was scary... and I got sidetracked... and it was fun... but I never actually got the definition I was looking for
