我再怎么笑都比不上她一骚
[wŏ zài zĕn me xiào dōu bĭ bù shàng tā yī sāo]
This is quite a colloquial expression, translating loosely as 'No Matter How I Laugh I Can't Equal Her Flirtation.' It implies that regardless of what this individual does, someone else (a girl presumably) has more influence or attracts more attention through flirtation. This expression includes some degree of vulgarity, indicating feelings of inferiority, envy or a light-hearted comparison between oneself and a certain kind of personality, perhaps focusing on charm and social appeal.
