LMAO
Acronym: Lighting My Ass On (Fire). The term was originally written as LMAOF, but people got even lazier over the years, and shortened it by one letter.
Sometimes, though, its true form is misspelled as "LMFAO". This is a common mistake, for the "F" is supposed to be at the end of the acronym.
