我宣他嫁给他我宣她娶道她
[wŏ xuān tā jià jĭ tā wŏ xuān tā qŭ dào tā]
This is a mix of colloquial internet expressions used playfully to announce relationships, akin to saying 'he marries him, I declare she marries me'. It’s humorous and non-serious declaration of virtual marriage or strong friendships in an exaggerated way common on social media.
