躺平

tǎngpíng

Literally says

to lie flat

Actually means

to quit the rat race and do the bare minimum on purpose

When to say it

Say it when you stop chasing promotions, mortgages, and perfect scores and choose a calm, cheap, small life instead. Half joke, half genuine life philosophy among tired young workers. Self-deprecating but secretly a little proud.

Hear it in the wild

我不想升职了,我决定躺平。

Wǒ bù xiǎng shēngzhí le, wǒ juédìng tǎngpíng.

I don't want the promotion anymore, I'm choosing to lie flat.

周末不接工作电话,躺平两天。

Zhōumò bù jiē gōngzuò diànhuà, tǎngpíng liǎng tiān.

No work calls this weekend, two days of lying flat.
