港女表一笑必挨草
[găng nǚ biăo yī xiào bì āi căo]
Literally translated, this nickname suggests 'a Hong Kong girl will get grass (insult) if she smiles,' which can be perceived negatively. In colloquial context, it implies that women may encounter unsolicited or inappropriate remarks when displaying friendliness or positive emotions in certain settings, reflecting social stereotypes or cultural behaviors around interactions with strangers.
