And why does no-one on Mumsnet ever FOCL (fall off chair laughing)?
As far as I can tell, the order of magnitude goes
LOL (there is also LOLOLOL etc, which makes no sense but is very expressive)
ROFL (that has a sort of friendly inclusive tone)
PMSL (can be a bit rude - you'd be more likely to use this one if you were laughing at someone)
LMAO (don't see that one very often).
Do you agree with how I understand them? And are there any more good ones?
