A Lolcat is an image combining a photograph of an animal, most frequently a cat, with a humorous and idiosyncratic caption in broken English referred to as "Kitty Pidgin" or "lolspeak". The idea originated on 4chan imageboards as "Caturday". The name "lolcat" is a compound word of "lol" (laugh out loud) and "cat". The phenomenon is also referred to as cat macros.
