The word lmaw was first typed in the popular pc game counter-strike. The word lmaw was meant to mean Light Multi-purpose Assault Weapon, but was misinterpreted to be a typo of lmao. People started to say lmaw while they didn't know what it actually meant, thus is became the ultmate lmao substitute.
