Mojack 

Slang term for Icelander, especially a rural one--popular term among US military personnel stationed in Iceland during WWII. Origin unknown.

That Mojack insisted vehemently that his cow was sick because of being sexually assaulted by our soldiers, but after our camp veterinarian diagnosed and treated her for a common bovine ailment, she made a full recovery; then the Mojack gave us some cheese to make amends.

Stealing a friend's song on MySpace.

I had this really awesome song on my page, which I loved until Karen myjacked it. Now no one will know which one of us found it first. What a douche!
