9.
An abbreviation of 'Choking On Air Laughing' or 'Choked On Air Laughing'. Similar to the terms, rofl or lol. It is another way to express that something someone said is hilarious. You could also say 'cool', by which you change Air to Oxygen.

Make sure your friends know what it means before using it, or you may sound a little weird.
Me: Haha, did you see 'The Date Movie'?
