嘴贱的人都该喝大姨
[zuĭ jiàn de rén dōu gāi hē dà yí]
Translates loosely as 'the one who loves gossiping should drink with their 'Big aunt’. Here, 'big aunt' is actually a humorous Chinese reference to having one's period, indicating the user's frustration or disdain towards those who talk excessively or spread gossip.
