Ghost Ninja; to randomly disappear on your friends while out and about.
Where is James? I checked everywhere, no clue. He must have hit us with the ghost ninja. Again, he was just next to me, man he is slick.

Sorry guys I had to Ghost Ninja last night I had this girl I couldn't be seen with, but couldn't pass on either.
