The word is alternately spelled kipe, kype, and kife. My best slang dictionary shows it showing up in the 1930s. Definitely US.
It doesn’t suggest and orgin, and gives the definition at pilfer, steal.
I’ve only heard it in a game or show that tried to use dialect. And I only remembered that after I looked up what it meant. It appears that kipe is the more common spelling, BTW. Kype gets stuff about skype on Google.
