rofsmslmao 

Rolling On the Floor Shitting MySelf Laughing My Ass Off.

The newest term indicating to the person you are typing to that you are laughing. It is also a protest against other terms of the same nature (such as 'lol', 'lmao', 'pmsl', 'rofl', 'roflmao') which have now become so over-used that their meaning have been rendered negligible. 'Rofsmslmao' as a rule must only ever be used if you are actually laughing (and not just giggling but literally wetting yourself) therefore this indicates to the person that they really have said/shown you/done something funny. It must also be spelt correctly otherwise it can lead to great confusion - e.g: rolling my ass off shitting on myself the laughing floor.
John: "So..."
Jimmothy: "rofsmslmao"
John: "wtf you think you're doing saying 'rofsmslmao' dude? I didn't even say something funny. Asshole"

Kenobi: "Forget it"
