It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO ("laughing my arse/ass off"), ROTFL("roll(ing) on the floor laughing") or ROFL ("roll(ing) on [the] floor laughing"), and BWL ("bursting with laughter", above which there is "no greater compliment" according to technology columnist Larry Magid). Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter-writing.
The list of acronyms "grows by the month" and they are collected along with emoticons and smileys into folk dictionaries that are circulated informally amongst users of Usenet, IRC, and other forms of (textual) computer-mediated communication. These initialisms are controversial, and several authors recommend against their use, either in general or in specific contexts such as business communications.
On March 24, 2011, LOL was formally recognized in an update of the Oxford English Dictionary.
