with hand on hip and elbow bent outward: to stand with arms akimbo.
Origin: 1375–1425; late Middle English in kenebowe < Old Norse *i keng boginn bent into a crook (i in, keng accusative of kengr hook, boginn past participle of bjūga to bend)
c.1400, in kenebowe, perhaps from phrase in keen bow "at a sharp angle," or from a Scandinavian word akin to Icelandic kengboginn "bow-bent." Many languages use a teapot metaphor for this, such as Fr. faire le pot a deux anses "to play the pot with two handles."
