wat lol means

"Lol" redirects here. For other uses, see Lol (disambiguation).
LOL (also written with some or all letters lowercase) is an abbreviation for laughing out loud[1][2] or laugh out loud.[3] LOL is a common element of Internet slang used historically on Usenet, but now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms such as ROTFL ("roll(ing) on the floor laughing"),[4][5][6][7] a more emphatic expression of laughter, and BWL ("bursting with laughter"), above which there is "no greater compliment" according to technology columnist Larry Magid.[8] Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter-writing.[9]
The list of acronyms "grows by the month",[4] 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.[10] These initialisms are controversial, and several authors recommend against their use, either in general or in specific contexts such as business communications.
