If you told someone: "I'll punch you to correct your temper!" you wouldn't have to do anything because they would laugh themselves to death!

Talgat has the right idea. According to this article, it doesn't refer to a specific consequence like kicking someone's ass or punching someone, it's a general promise to show you "what's what" in some way or another: https://en.wikipedia.org/wiki/Kuzma%27s_mother

We also say just "I'll teach you!" or "I'll show you!"

Ха-ха! Но ведь эти слова Хрущёва как только не переводили: от "I'll show you Kuzma's mother!" до "I'll bury you!"😠😠😠

Мы тоже. Я вас проучу! Я вам покажу!

It's that simple. Nothing like that confusing pileup of threats that Tania published.

Copy & paste - that simple)

ugh 😑
