According to Wikipedia, a lolcat is "an image combining a photograph, most frequently of a cat, with a humorous and idiosyncratic caption in (often) broken English—a dialect which is known as “lolspeak,” ”kitteh,” or “kitty pidgin” and which parodies the poor grammar typically attributed to Internet slang. The name "lolcat" is acompound word of the words "LOL" and "cat".
After reading this I was even more appalled to learn that this supposed dialect has been given not only one name, but three different names. I guess nothing should surprise me in this day and age of chatlish.
