Defi-jack 

The act of someone stealing your definition on urban dictionary. It starts by you making up your own clever word that you think would be perfect for Urban Dictionary only to see that someone already defined it 3-to-5 years earlier. Results of being defijacked include, but are not limited to: complaing about it on Facebook and or Myspace, telling all your friends that the first definitions were actually you, and suicide.

After using the term "CTS"(Chuckle To Self) for about a week, Sam decided to put it on UD. You can imagine his disapointment when he saw that some punk had Defi-jacked it 3-to-5 years before hand. He immediatly started complaing about it on Facebook and he continued his rant until he decided to kill himself.

Typical Urbandictionary Definition

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.

see roflcopter I think its about the 6th definition down. That is a prime example of a typical urbandictionary definition.
