galibi
When a man says he has to be with his wife or girlfriend, but it's just a fancy way of saying he doesn't want to do the thing he was asked to do.
'I can't go to the bar, I'm with my girlfriend.' He was at home eating chips.
'Galibi! I have to be with my wife.' He was with his brother.
'I can't come to the party, I'm with my wife.' She was at work.
