Is this what they mean by chutzba?
Yup. Leo Rosten in The Joys of Yiddish defines chutzpah as "gall, brazen nerve, effrontery, incredible 'guts,' presumption plus arrogance such as no other word and no other language can do justice to."
The old joke to define chutzpah is of a boy, having just been convicted of murdering his parents, begging the judge for leniency because he is an orphan.
