gentleman of the four outs

An upstart. The four "outs" in question (that the person is living without) are manners, money, credit, and wit. I can't stand the young new partner at the firm—I can see that he's a gentleman of the four outs. OK, that's enough moping around the house—I didn't raise you to be a gentleman of the four outs. You need to start applying for new jobs. Maybe he's not a gentleman of the four outs, but he certainly has no manners!
