脏话是女汉子保护色
[zàng huà shì nǚ hàn zi băo hù sè]
'Dirty words are protective coloration of a tomboy.' It signifies that using foul language acts as a shield for toughness or masculinity projected by a tomboy or a 'woman man', which usually denotes a strong and independent woman unafraid to use rough language as a form of self-expression or defense.
