any unwanted or unwelcome advertisements that are sent over the internet, usually in the form of an e-mailand usually in excess.

the term is believed to have orignated form a show call, "monty python's flying circus", during a certain sketch about a resturant that served spam (the canned meat) with all of its meals. it was unwanted and excessive, just like the e-mail.
ugh... i wish this spam would go away.
