脏话是女汉子的伪装
[zàng huà shì nǚ hàn zi de wĕi zhuāng]
'Dirty words are used by tomboys to hide themselves.' In China, saying 'bad words' generally indicates bold and outgoing personality rather than real rudeness, and this nickname can express self-protection or self-awareness. But attention needs to be paid here: such usage should be done with respect for different cultural environments.
