Meme

A meme is a quantum of viral information. It usually gains its viral quality because people find it funny.

Many Fark.com headlines contain memes. Your dog wants steak, EVERYBODY PANIC, the Sun is there, and so forth.

Memes are big and small... LOLcats are a fairly large meme which contain many smaller memes (Cheezburger, invisible bike, etc.).

i think meme is a pretty cool guy. eh overuses self and doesn't afraid of anything!
