你魅你媚你妹
[nĭ mèi nĭ mèi nĭ mèi]
On surface, this phrase plays on alliteration, repeating similar sounds. However, the third word is a provocative play, literally implying a nonsensical insult towards another. In slang Chinese Internet terms, it could indicate frustration and sarcasm, but generally it’s quite colloquial.
