脏话是女汗子的保护色
[zàng huà shì nǚ hàn zi de băo hù sè]
This translates to 'Cursing is a sweat-stained protective color (protection) for women'. The meaning here may be more complex. It might imply that in certain contexts, using vulgar language allows women to set up boundaries and gain respect. This is somewhat specific to some cultures where women traditionally have less power. Through the use of dirty language, one can show toughness or independence.
