A funny, good looking guy, usually young but not neccessarily. Very cheeky and jack-the-laddish. Often intelligent and mature for his age, quick-witted especially around people he's just met. The kind of guy you see in a corner at the party telling girls about travelling stories. Like a party animal but not as wacky or drunk.
Hey, that guy looks like Ant, I can't believe he's pulling that joke off.
I went to a party last night and this absolute Ant was there, nicked all the pussy.
