Что такое lol?

(англ.) Laughing out Loud - "сильно смеяьтся", "очень смешно". Относится к интернет-сленгу и используется преимущественно в чатах, электронной переписке, а также SMS-переписке.

Among the earliest Internet slang terms is LOL,[16] an indication of appreciation of humor, literally meaning “Laughing Out Loud” or “Lots Of Laughs”.[18] It could also mean lots of love, but this is rare, if encountered at all in online culture.[19] Similar acronyms were quickly added to the lexicon, including ROFL (“Rolling On the Floor Laughing”), LMAO (“Laughing My Arse/Ass Off”), and the combination of the two; ROFLMAO ("Rolling On the Floor Laughing My Ass Off"). A more uncommon version of ROFL is FOFL meaning "F"alling "O"n "F"loor "L"aughing. [20][21] Derivations of the acronym quickly became incorporated into the Leet vocabulary. LOL can also be displayed typed as lawl. ROFL can also be combined with LOL—ROFLOL (Rolling On the Floor Laughing Out Loud). The word "lawl" is now starting to be used, which is the spelling of the pronunciation of lol as a word.
