Get the Jack Hammermug. Submitting this because all the definitions are wrong. This term originated back in the 90's when Jack in the Box made national news from a bunch of stores getting people sick with E. Coli bacteria, which is basically from shit contamination. Hence, Jack in the Crack was born.

Get the jack in the crackmug. 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.
