In English, it would be similar to casually saying "yeah, sure!".
Like:
* Can I borrow your pen?
* Yeah, sure!
* * *
*
*
, is also correct but it's less standard. I never heard people actually use that in my experience. But people talk in all kinds of weird ways. Imagine someone saying the following in English: `Yeah bruh`
It's not standard but some people actually talk like that so culturally speaking, it's not wrong.
