Chutzpah is great! There are tons of great Yiddish words. Some of my favorites are schvitz (to sweat; alternatively a sauna), schlep ([traveling] an annoying distance), mischigas (nonsense or nutty behavior, or kinda similar to a clusterfuck), noodge (kinda like a pest, but said with some affection), zaftig (pleasingly plump, like Christina Hendricks), and kvell (to be really happy/proud, opposite of kvetch).
