Someone who puts there name up on urban dictionary saying how great or awesome they or a boyfriend or girlfriend is just so they seam more important in the world.
Where people go to see sexual and naughty stuff on here for fun! Add a k and have some fun!! this is how people get their freaky ideas!!
Yo!! Wifey and I found this shit on the urbandick, it got hot as fuck with her last night if you know what I mean! She used that Watermelon sugarstuff on me.
When you find out how awesome it is that Urban Dictionary has gone to the lengths they have to prevent multi-voting of definition entries on this website.
When someone, most likely a prepubescent 13 year old, writes a sex definition for something which has nothing to do with the word you looked up.
Theoretical example - I look up forum troll, because i've seen it used extensively on forums, and never understood what it meant. One of the definitions will most likely be something like this -
"While ur fucking ur girl from behind in teh dark, u put a dildo instead of ur dick in her hole, u then grab a cardboard box full of troll dolls and begin throwing them at her, all the while yelling ATTACK OF TEH FORUM TROLLS!!!"
A typical urbandictionary definition deserves deletion, it contributes nothing to the viewer's knowledge, and only serves to prove how idiotic the poster is.
