WAY back in the early days of the net, people would send files and mail to the 1-2 other people they knew who knew how to access the internet.

Rumor has it that one day a geek was sent 100 bits of unsolicited mail by a guy who only knew how to do that with computers and was trying to impress the geek. The geek became irritated and over dinner that night told his friends about it saying "Some Poser Annoyed Me".

Hence the term SPAM was born.
