Lolcats are a type of meme that include but are not limited to a cat picture and captioned text written in the distinct lolcats cute speak, as if narrating what the cat pictured is saying or thinking. They can also include motivational poster style memes, gifs, and photoshops. These types of memes were a defining aspect to mid to late 2000's internet culture, also contributing to different later memes like doge speak, post-irony, and celebrity cats (like Grumpy Cat, Lil Bub, and Colonel Meow).

Lolcats speak often comes off as childish, including an addition of lisp in the text, as well as cute comments, relatable comments, and overall absurdity.
