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.

Get the Dirty Jack mug.A dildo jack-off is the preferred masturbation technique my cadet roomie uses to give a cumgasm -- he fucks me with a 10" dildo up my boy-hole, and jacks me off until I have a cumgasm, while he's fucking me with the dildo and I'm sucking his dick.
My cadet roomie gave me a dildo jack-off, and we both enjoy it -- I was sucking a cumgasm out of him, and enjoying being fucked as I blew my load!
