Spam

Spam originally referred to Spam (food), a canned meat product sold by the Hormel Foods Corporation. Since then, many other uses of the term have emerged.
* Spam (Monty Python), a Monty Python comedy sketch. The "Spam" in the sketch refers specifically to the meat. Most later uses of "spam" refer in one way or another to undesirable repetition, and this sketch is considered to be the most likely source of such uses of the term.
