No Bant 

Someone who does not partake in banter; someone who is no fun, preferring to stay in/work rather than going out with mates

Guy 1: "Mate you comin' out tonight?"

Guy 2: "Nah man, I have work to do..."

Guy 1: "Your'e a No bant!"

no banter 

The type of male who always seems keen to stay in the crowd. It's only after 15 years of friendship you get left alone in a bar with him. It suddenly dawns on you that this man has no conversation at all.

Whatever happens tonight lads - don't leave me alone with Simon Keir. He has absolutely no banter.
