1. slang Someone with very bad body odor; a smelly or unhygienic person. From Yiddish. I had to sit next to a real shtunk the whole train ride home. Sorry I'm such a shtunk—I've been out working in the garden all day and haven't showered yet!
2. slang A rotten, worthless, or utterly incompetent person; someone who is extremely petty, negative, and dishonest. From Yiddish. I just don't understand why anyone would vote for a schtunk like her. She has all but admitted to tax evasion, for Pete's sake! Jeff is managing the project? That schtunk couldn't manage his own sock drawer. I wish that shtunk would bring a bit more to the office than his constant carping and negativity.
