LOL (also written lol) is a common element of Internet slang used, historically, on Usenet but now widespread to other forms of computer-mediated communication such as instant messaging, and even spread to face-to-face communication. It is an acronym for "laughing out loud"[1][2][3] or "laugh out loud",[4] or, less commonly, "lots of luck" or "lots of love".[3] "LOL" is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms such as "ROFL" (or "ROTFL") ("roll(ing) on the floor laughing"),[5][6] a more emphatic expression of laughter, "LMAO" ("laughing my ass off").[7] ROFL and LMAO are sometimes combined into ROFLMAO (rolling on floor laughing my ass off).
