It's original definition was "Mini Internal Chuckle" (also written occasionally as "Mild inner Laugh"), used as a brief acronym to denote great amusement in chat conversations.

Invented to replace the inane "LOL" - which as well as being fucking annoying - is also bullshit as no-one ever "Laughs out Loud" when reading the musing of turds on the internet
Turd: LOL, that was funny
Turd2: MIC, not really - however, we're laughing at you, not with you.

General term for an Irish man, more commonly spelled Mick. Recently it has come to particularly apply to either the average Irish or Irish-American nob end that think they're smart and don't drink too much and are fantastic at football, but in reality have delusions of grander, are usually alcoholic, possess an IQ less than that of a dead fish, are always getting locked up for stupid crimes, couldn't kick the shit out of a dead pig and have less football skill in their entire bodies than George Best had healthy livers (i.e. none).
What do you call an Englishman surrounded by a thousand micks? Warden! Haha, fucking micks.
