The Lolcat meme is has been exploding lately. Lolcats or cat macros are those weird photos of cats (sometimes other creatures) doing strange things and using bad grammar. Recently they have been popularized via creative Twitter error messages.
Anil Dash recently wrote a great post about the whole Lolcat phenomenon.
UPDATE: Well I’m legit now, I Can Has Cheezeburger? has officially cataloged and tagged my Ika Zaru Lolcat.
