A playful, satirical response to be used in situations where somebody refers to a person or group that you ARE, in fact, familiar with (usually somebody popular/famous), but wish to mock.

The inquisitive tone would normally suggest that you had no prior knowledge of that person/group's existance, but in situations where the person you're talking to knows that you know who they're talking about, it's an implied dismissal (i.e. you're basically saying that you don't give a shit about whoever they're talking about, calling them a nobody or a has-been).

It refers to a situation when nothing is absolute or certain yet, when things are still in the process and one cannot guarantee what the result would be like.
"I am not sure what is going to happen. It's still a who-who situation."

"I have not made my mind about this yet. It's still a who-who situation for me."

"They might be in a who-who situation, let's give them some more time to think."

"You are still in a dilemma? Wow you are such a who-who"
