LMFAO

LMFAO is an acronym that stands for "laughing my freakin' a** off," which is typically used online and in text messages. It is a more intense version of the popular LMAO acronym, which is only reserved for the funniest of situations.

If the acronym is used on social media, it most likely accompanies a really funny meme. It may be offensive to people who easily get offended by vulgar acronyms.

Chonky people use LMFAO to stand for "laughing my fat a** off." Someone who sends you this acronym wants you to imagine them laughing so hard that they are losing weight from their large posterior.

While LMFAO can mean either "laughing my fat a** off" or "laughing my f***ing a** off," its specific meaning is not actually that important. What's most important is that the person you're chatting with is laughing, likely as a result of something you said.
