Where does LMAO come from?

The expression to laugh one’s ass off goes back to at least the 1950s, when J.D. Salinger used it in his classic novel The Catcher in the Rye. Similar to expressions like work one’s ass off or laugh one’s head off, the phrase to laugh one’s ass off conveys intensity and extremity—specifically in LMAO‘s case, of tremendous hilarity. In the 1840s, for instance, Charles Dickens jokingly claimed he had “written his head off” in a letter to a friend.

One of the earliest uses of the abbreviated LMAO is a transcript of a game of Advanced Dungeons & Dragons from December 1990. One of the players, playing as their elf character Torquin, uses LMAO at one point during the game. LMAO spread with the rise of the internet and text-messaging in the 1990s.

How is LMAO used in real life?

LMAO is used so frequently in chats and on social media that you can find it almost anywhere on the web and in text messages.


In fact, the abbreviation is so popular that the electronic dance music duo LMFAO have said they got their name after their grandmother responded with a more vulgar version of LMAO (LMFAO) after they told her their original idea for a band name: The Sexy Dudes. Perfect call, Grandma.

People sometimes further intensify the sentiment of LMAO but adding strings of Os at the end of the abbreviation, e.g., LMAOOOOO.

LMAO is also sometimes referred to as an internet acronym or initialism.
