A person who you find so absolutley revolting and so chronicly annoying that you want to label them a cunt but are prevented from doing so because said person is that much of a pathetic lowlife and scumbag they don't quite deserve to be labelled a whole Cunt but rather a smaller portion of Cunt Ie: a Cuntchop.
