• noun a foolish or stupid, annoying person. A vulgar but not taboo term of abuse which had existed in British slang usage since the 1950s (its exact date of origin is undetermined), coming into vogue in the mid-1970s. Various etymologies have been proposed for the word; ‘pillicock’ was a late medieval term for the penis, sometimes used as an expression of endearment or affectionate abuse; pillocks has also been explained as a rural term for rabbit droppings, or as a synonym for the testicles (pills) employing the diminutive or affectionate suffix ‘-ocks’ (as in the case of balls and bollocks).
