Instant messaging lingo.
During an online
conversation if one finds
something funny, but not funny enough to laugh, one might have a very slight outburst of breath from the nose. This is a 'ffins.' AKA a reversed sniff.
A word for those who are sick of people that say lol, lmao, and rofl every single thing.
A subtle way of telling someone online that you found what they said funny, but you're not laughing.
