We all know about the expression "WTF" - what the fuck in English. It can be reflected with this face:
And it can be described as:
- What are you talking about?
- Are you serious?
Or many more similar sentences.
Is there any equivalent in Spanish? I thought about the following, but it might sound a bit harsh or rude:
- ¿Qué coño...?

By the way in South America we say "¿Qué carajo?". In TV and comic books I sometimes see "¿Qué cuernos?", so that can be a less rude alternative.
