What does it mean when a Pole winks at you?

Is that a way of greeting or it's a way of flirting?

A way of recognizing that only you and the recipient know a piece of information

Yes it can be flirtatious - if I saw a cute girl the other side of the room my first move would be a big smile - a wink is more flirtatious than a smile :)

Very often this.

It can also be an eye blinking tic.
It can be cured.

You're delusional, have delirium or are dreaming. Should consider seeking a medical help.

You answer is illogical. It suggests the OP is delusional about being winked at. In this way you refuse to acknowledge that the act of winking takes place .

Hmm, are you sure???

He might have "pink eye" its been going around over there, worst than the ChinaVirus.
