The phrase comes from lan shou xiang gu, a Mandarin internet pun on nan shou xiang ku, meaning feeling sad and wanting to cry. It spread in China in 2016 after a viral video of a young man using the playful pronunciation to describe heartbreak, and the wording quickly became shorthand for exaggerated sadness in comments, captions and short videos. Because the joke relies on sound rather than spelling, the two syllables alone still signal comic misery to audiences familiar with the meme, even without the full phrase.
