win [MIT] 1. vi. To succeed. A program wins if no unexpected conditions arise, or (especially) if it sufficiently robust to take exceptions in stride. 2. n. Success, or a specific instance thereof. A pleasing outcome. "So it turned out I could use a lexer generator instead of hand-coding my own pattern recognizer. What a win!" Emphatic forms: `moby win', `super win', `hyper-win' (often used interjectively as a reply). For some reason `suitable win' is also common at MIT, usually in reference to a satisfactory solution to a problem. Oppose lose; see also big win, which isn't quite just an intensification of `win'.
