n 1: trademark: soft processed American cheese
The Jargon File (version 4.4.7, 29 Dec 2003):
[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.
