Internet Memes
Internet memes are catchphrases or images that spread quickly, peer to peer, across the Internet. Many Internet memes have originated on 4chan, usually /b/, as its fast moving, crowd psychology nature enables content to quickly be passed on to large numbers of viewers. Other memes originating on the site have gained media attention of a lesser degree. These include "So I herd u liek mudkipz", which involves a phrase based on Pokémon and which generated numerous YouTube tribute videos, and the term "an hero" as a synonym for suicide, after a misspelling in the MySpace online memorial of seventh grader Mitchell Henderson. 4chan, and other websites, such as the satirical Encyclopedia Dramatica, have also contributed to the development of significant amounts of leetspeak.
