A term used to describe someone/something who has really annoyed you, who you would normally refer to out loud as a Cunt
but can't because of your Boss or someone who might be offended and sack you. It's a mixture of the childish term Willy
to describe male gentials and the derogertary term Cunt
to describe female gentials, and even though you may sound like a complete twat saying it out loud, because they won't understand what you've said your less likely to get sacked! or punched.
