The collective noun for memes

I think there's a need for a collective noun for memes. This is partly because of the way memes sometimes tend to clump together - in conferences and churches for example - or in the minds of the paranoid or obsessed.

The resulting effects are rather like a flock of birds or a school of fish...

Here are some of the more noteworthy proposals so far:

• a library of memes
• a plague of memes
• an epidemic of memes
• a colony of memes
• a swarm of memes
• a pool of memes
• a plethora of memes
• an infestation of memes
• a hash of memes
• a copy of memes
• a sneeze of memes
• a contagiousness of memes
• an infectiousness of memes

There's also a proposed collective noun for internet memes:

• a roflcopter of internet memes

The sources for many of those are here and here.
