我是柠檬酸到心痛
[wŏ shì níng méng suān dào xīn tòng]
This username conveys a feeling of sourness and pain deep in one's heart, comparing the intense jealousy or bitterness to the sharp tanginess of a lemon. Lemon is often used in Chinese internet slang to express the bittersweet feeling caused by jealousy or envy, so this name suggests that someone feels heartache because of a painful experience.
