A lolcat (pronounced /ˈlɒlkæt/ lol-kat) is an image combining a photograph of a cat with text intended to contribute humour. The text is often idiosyncratic and grammatically incorrect, and its use in this way is known as "lolspeak" or "kitty pidgin".
"Lolcat" is a compound word of the acronymic abbreviation "LOL" and the word "cat". A synonym for "lolcat" is cat macro, since the images are a type of image macro. Lolcats are commonly designed for photo sharing imageboards and other Internet forums. Similar image macros which do not actually feature cats are often simply referred to as "lols".
