没治 is a colloquial Chinese expression with two opposite meanings depending on context. Literally 'no cure', it means 'hopeless', 'incurable', or 'beyond help' — used for situations or people that seem unfixable. In slang, however, it flips to mean 'unbeatable' or 'awesome', as strong praise (similar to 'can't be beat'). The word is commonly used as a stative verb, often followed by 了 (∼了!).
