Yiddish term for courage bordering on arrogance, roughly equivalent to “nerve” (in the slang sense): “It took a lot of chutzpah to make such a controversial statement.”
1892, from Yiddish khutspe "impudence, gall" from Heb. hutspah. The classic definition is that given by Leo Rosten: "that quality enshrined in a man who, having killed his mother and father, throws himself on the mercy of the court because he is an orphan."
