sig virus n.
A parasitic meme embedded in a sig block. There was a meme plague or fad for these on Usenet in
late 1991. Most were equivalents of "I am a .sig virus. Please
reproduce me in your .sig block.". Of course, the .sig virus's
memetic hook is the giggle value of going along with the gag; this,
however, was a self-limiting phenomenon as more and more people
picked up on the idea. There were creative variants on it; some
people stuck `sig virus antibody' texts in their sigs, and there
was at least one instance of a sig virus eater.
