Anything that is done in the style of a cunt. An item that is offensive, unhelpful, insulting, obstructive or demeaning. Best used in situations where use of the word cunt may result in harm to oneself, and the subject isn't intelligent enough to understand the implications (see example).
If a manager treats his staff badly he has a 'cuntional' management style, rather than him simply being called a cunt, thus reducing the likelyhood of being sacked.
