结婚我要情敌当伴娘
[jié hūn wŏ yào qíng dí dāng bàn niáng]
Literally means 'For my wedding, I want my rival/love rival to be a bridesmaid.' This suggests dramatic irony; the user imagines having their competitor attend their most significant day as something symbolic, humorous, or vindictive. It could be taken playfully or reflect genuine competitive sentiments in matters of love.
