真香

zhēnxiāng

Literally says

really fragrant

Actually means

I swore I would never, and now I love it

When to say it

For when you mocked something and then ended up loving it. You swore you would never download that app, now you cannot quit it, zhēnxiāng. A self-mocking confession of your own flip-flop, and everyone in China gets the reference instantly.

Hear it in the wild

我之前说不买，现在真香了。

Wǒ zhīqián shuō bù mǎi, xiànzài zhēnxiāng le.

I said I wouldn't buy it, and now I'm obsessed.

说好不追剧，结果真香。

Shuōhǎo bù zhuījù, jiéguǒ zhēnxiāng.

Promised I wouldn't binge the show, and here we are.
