Laughing In Real Life for lol is abused and only said when something is amusing or when nothing else can be said. LIRL is used when people really are laughing in real life. It was Invented by THEE Clique and used primarily by them, but it is slowly spreading throughout the internet.

L.I.R.L. means 'Laughing In Real Life'. It goes along the same lines as 'LOL' only it is a literal expression for moments when you are actually laughing in real life. It is not as flexible as LOL, which can be applied to anything amusing or likeable.
Laughing In Real Life (internet only)
Because of the over use of comments like LMAO, or LOL, this indicates that you REALLY ARE laughing, and are not simply saying LOL for lack of anything better to say. This is not widely used, and has only come into existence because of some of my friends.
Bill: Jim got his testicles caught in the door, it was so freaking funny, he screamed like a little girl.
Joe: LIRL *dies laughing*
