🌿 The rich don’t lick the yogurt’s lid.

Have you tried yogurts in Korea?
Korean yogurts get on the lid easily, so most of Koreans lick the yogurt on the lid when they throw the lid away.
This ‘licking yogurt on the lid’ looks too frugal (but it is so common and natural!), and we are not as comfortable as in the Crazy Asian, so the meme has come, “The rich don’t lick the yogurt’s lid.’
We don’t use it as a phrase often, but it can be used as a background of jokes.

🐶 난 부자야(I’m rich).
🐸 왜? (Why?)
🐶 요거트 뚜껑 그냥 버렸어(I threw the lid away with the yogurt.)
🐸 오... (Oh..)

In this cartoon, she is a cashier and suprised a lot because this guy(the rich) licks the yogurt lid.
