In Korean, annoyance is often expressed by “bouncing” the last syllable, kind of like a whine.

I know this is common among children/siblings of all languages.

What seems to be unique in Korean is that it’s done by all ages, men and women. To the degree where it’s clearly a feature of the language.

Are there any other languages like this?
