What Does the Acronym LMAO Mean?

The acronym LMAO stands for “laughing my ass off.” LMAO probably comes from LOL, an internet slang term that stands for “laughing out loud.” LMAO is a heightened version of LOL, and it is used to react to something that is very funny. 

LMAO and LOL are often used on social media sites like TikTok, Twitter, Whatsapp, Facebook, Instagram, and more, similar to slang terms like JK, leet, WTF, TTYL, THX, noob, LML, and TIA.

Message boards, chat rooms, and instant messaging spurred the beginning of internet slang acronyms in the 1990s alongside the invention of text messaging. Thanks to the numeric keyboard and message character limits, texts had physical limitations, so people used abbreviations to circumvent this. You can write LMAO in either uppercase or lowercase.

Internet slang terms and chat speak are often used alongside emojis as well. Emojis can be very useful in expressing emotion quickly and are often used with slang abbreviations. Emojis used to be known as emoticons and were formed by typing out different keys to make symbols. Nowadays, most people do not use emoticons but opt for emojis instead.
