LMAO is an acronym that means "Laugh your ass off". Used on the networks, it allows to quickly express the fact of laughing a lot.
Acronyms are increasingly present in spoken language. There is not a day when you don’t hear LOL, POV or JSP. So it’s true that it’s quicker to use these little words rather than a long sentence. But sometimes, some people can get lost or don’t know this gibberish at all.
