velveeta

[Usenet: by analogy with spam. The trade name Velveeta is attached in the U.S. to a particularly nasty processed-cheese spread.] Also knows as ECP; a message that is excessively cross-posted, as opposed to spam which is too frequently posted. This term is widely recognized but not commonly used; most people refer to both kinds of abuse as spam. Compare jello.
