A "Spicer" is someone from Dublin who thinks they are hard/mad. Also known as a madt cunt. They will more than likely spike their hair, where adidas tracksuits etc.. Similar to the english "chav". A Spicer is not as hard as a Dublin knacker. It comes completely natural to a knacker to act hard where as a Spicer can sometimes try to emphasise their knackeryness to make them seem .. more knackery.
