My 16 yo DD came downstairs just as I was explaining Fridge Cunt to DH and just about lost the plot; granted, we're in the US and 'cunt' over here is The Word Wot Shall Not Be Spoken Ever.
Not that that stops me from using it with vim and vigour, especially when certain deformed Cheez Doodles politicians are on the TV or when I read about someone being so cunty as to hog an office fridge! She may have to just get used to it.
