have the gall to do
have the gall to (do something)
To be bold and brazen enough to do something. I can't believe that intern had the gall to ask for a week off on her first day. A: "I can't believe their coach had the gall to pull the goalie with so much time left." B: "Yeah, but if they tie the score, he'll look like a genius."
have the gall to do something
Fig. to have sufficient arrogance to do something. I bet you don't have the gall to argue with the mayor. Only Jane has the gall to ask the boss for a second raise this month.
