The lolcat thing might have peaked some while back but it's cute. For the uninitiated lolcat is the secret language of felines. It's got devotees who have translated the Bible into cat lingo. (God is "Ceiling Cat," derived from a photo of a pussy paw dipping down in consecration from a suspended ceiling.) A cat is a "kitteh". Food is generalized as "cheezeburgerz". There are certain established conventions in lolcat, but if you just want some fun, you can make up your own.
