娘炮 - how do you pronounce this word/phrase?
Oh, get you a Taiwanese news (at 0:18 by the anchor, 0:58 by a student and 1:24, 1:56 by himself) about that, where it's pronounced as "niáng pào". I can tell that we use this word in mainland China too, here is the proof.

It refers to a sissy (a boy that other boys dislike because he prefers doing things that girls enjoy).
