LFNR 

It means "Laughing for no reason", which happens when you suddenly get an insuppressible urge to laugh, even when there's no real reason to do so. This can also be used as an excuse when you thought of something funny/embarrassing and accidentally laughed in public.

Person 1: *giggles*
Person 2: What's so funny?
Person 1: Oh just LFNR.
