"Hink pinky" isn't a real phrase or gesture. It sounds like a made-up word.
Here are some common ways people express confusion:
* Phrases:
* "I'm confused."
* "What do you mean?"

* "Huh?"
* "Wait, what?"
* Gestures:

If you're looking for a fun way to express confusion, you could invent your own gesture or phrase!
For example, you could:
* Make a silly noise like "Boop!" or "Zzzzt!"
* Create a hand gesture like putting your hands on your head and spinning around in circles.
* Use a silly word like "Baffled" or "Bewildered."
