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.
