Woft--
Spam is a pork "luncheon meat" in a can. It's pink, slimy, greasy, well, you get the picture...:p It's a product of the Hormel Corporation, a canned meat supplier. I haven't eaten any in years.
Here's a
link to an unofficial web site outlining a history of the product & name. I make no claims for authenticity of the info therein.
You can check for Hormel's web site, too, of course.
Gotta run now.
