Ye Kya Bak Rahe Ho !exclusive! -
If that was your intended meaning, clever wordplay. If you were genuinely asking what someone said, I can help translate or clarify.
It sounds like you're mixing Hindi slang with English. "Ye kya bak rahe ho?" roughly translates to "What nonsense are you spouting?" or "What are you rambling about?" in a casual/abrupt tone. Adding "— interesting feature" makes it feel like a humorous or sarcastic tech/product review — as if someone called a new app update nonsense but then admitted it's an interesting feature. So you're likely joking: "What are you blabbering about? Oh wait, that's actually an interesting feature." ye kya bak rahe ho
