LOLCODE is an esoteric programming language inspired by the language expressed in examples of the lolcat Internet meme. The language was created in 2007 by Adam Lindsay, researcher at the Computing Department of Lancaster University.
The language is not clearly defined in terms of operator priorities and correct syntax, but several functioning interpreters and compilers already exist. The language has been proven Turing-complete.
