真香

From 2014 TV show X-Change (season 8), on which Wang Jingze said:

我王境澤就是餓死，死外邊，從這跳下去，（也）不會吃你們一點東西！ [MSC, trad.]
我王境泽就是饿死，死外边，从这跳下去，（也）不会吃你们一点东西！ [MSC, simp.]

From: X-Change (season 8)

Wǒ Wáng Jìngzé jiùshì èsǐ, sǐ wàibiān, cóng zhè tiào xiàqù, (yě) bùhuì chī nǐmen yīdiǎn dōngxī! [Pinyin]

I, Wang Jingze, would rather starve, die outside, or jump out of this building than eat food you give!

at first, but after only 2 hours he said 真香 (zhēn xiāng, “really fragrant”) when he was having supper.

真香

1. (Internet slang, neologism) used to describe someone doing something that he or she had previously sworn never to do [from 2014]
2. Used other than figuratively or idiomatically: see 真 (zhēn),‎ 香 (xiāng).
