According to Haig, M. (2001) and Franzini, L.R. (2002), LOL is an abbreviation for laughing out loud, or laugh out loud (Egan, M, 2002), is a common element of Internet slang. It was used historically on Usenet but is now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of much initializes for expressing bodily reactions, in particular laughter.
