what cunt
WAHT CUNT! Self discriptive term that outlays ones feelings of hostility towards another. 
Also used as a term of endearment.

Customer- Have you got any peanut butter in your shop, shop lady?
Shop lady- What cunt?

Man- hey i heard you called my girlfirend a slut
Man 2- WHAT CUNT?
Man- Nothing. Sorry
Man 2- WHAT CUNT!
Man- No seriously it was just a joke, she is a slut anyways, I hate that fucking slut.
Man 2- WHAT CUNT?
Man- I fucked your mum
Man 2- WHAT CUNT? 

Its quite obvious that in this case here man 2 suffers from a common syndrome called whatcuntitis, which can be caused from over abuse of this term.
