少年痴货最帅比
[shăo nián chī huò zuì shuài bĭ]
Translating literally, this is a mix of casual slang terms where it describes a teenage boy ('Shao nian') who acts foolishly or crazily ('chi huo' meaning silly or crazy to some extent) is actually very handsome. The last character '比' here adds emphasis on being extremely cool or good-looking
