But you're the one calling

"But you're the one calling" Is a translation from a polish version of "who asked" or just straight up telling someone that they're bragging about an irrelevant topic or just another way of saying "who asked?"

Your girlfriend slept with 3 guys before you!

Unless she does when I'm in a relationship ship with her I don't mind.

I was one of them.

But you're the one calling.
