hang up

hang up one’s sword or gloves or fiddle. Quit, retire, as in He’s hanging up his sword next year and moving to Florida. The noun in these expressions refers to the profession one is leaving—sword for the military, gloves for boxing, and fiddle for music—but they all are used quite loosely as well, as in the example.

hang up one’s hat. Settle somewhere, reside, as in “Eight hundred a year, and as nice a house as any gentleman could wish to hang up his hat in” (Anthony Trollope, The Warden, 1855).
