脏话是女生的保护色
[zàng huà shì nǚ shēng de băo hù sè]
The phrase '脏话是女生的保护色' means 'cursing/ bad words are girls' camouflage'. In many cultures, especially traditionally in China, girls were expected to be gentle and elegant, and the act of swearing was thought of as a way for modern females to protect themselves or express strong emotions. It signifies breaking gender norms and shows toughness or being able to stand up for oneself, rather than adhering to old-fashioned ideas of femininity.
