chutzpah

Chutzpah refers to extreme self-confidence or audacity, often to the point of being rude, cheeky, or pushy. It describes a person who acts as if the rules don't apply to them, usually in a way that is surprising or even impressive because of its sheer nerve. While it can be used to describe someone being genuinely obnoxious, it is often used with a sense of grudging admiration. It is a Yiddish loanword that has become common in English, typically used in casual conversation to describe someone who has the "guts" to ask for something unreasonable or do something bold.
