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
Falling
On
Floor
Laughing.
[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.
More recently, "lol" has been popularized as a noun, most frequently seen pluralized as "lolz" or deliberately misspelled "lulz", as in "I did it just for the lulz".
