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.

gktfo means got knocked the fuk out, which would be past tense for ktfo. gktfo is more funnier to say, if i do say so myself.
