A short way to express laughter in typing, rather than type "ha ha" which might be mistaken to somebody as a more offensive laugh. A more convenient way to express laughter than "I'm laughing hard." If it is said in person, this could mean the speaker is incredably lame, stupid, or ignorant, or is addicted to games.
John: So my friend got tripped today.
Jim: Ha ha!
John: Hey, shut up, he wasn't expecting it!
Jim: Err.. what I meant to say was: lol that sucks
John: Oh, okay.
Jim: Ha ha!

A lolcat using "LOL"
LOL or lol, an acronym for laugh(ing) out loud or lots of laughs, is a popular element of Internet slang. It was first used almost exclusively on Usenet but has since become 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 for more emphatic expressions of laughter such as LMAO7 ("laugh(ing) my ass off") and ROFL (or its older form ROTFL; "roll(ing) on the floor laughing"). Other unrelated expansions include the now mostly obsolete "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.
LOL was first documented in the Oxford English Dictionary in March 2011.
