An unearthly rock formation in the shape of an erect penis complete with testicles in the Mahon Valley in the Comeragh Mountain range, pronounced man valley, which is an unfortunate enough coincidence. Legend has it that if you spit on Dicky Rock you will receive the gift of the shag!
yet another term meaning eejit but describing a person of not much use. e.g. "that useless sooskin couldn't pour shit from a shoe if the instructions were on the heel"
