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!
'A thing of' is a very Irish way of describing an inanimate object, usually a container or packaging of sorts. Be it down to laziness, or actually not knowing the name of what the object is, this expression has many uses.
Usually said after saying something smart or intelligent.
A longer version of the sentence is 'Up here for thinking, down there for dancing, out there for shaking and down here for making' Usually one would point to their head then feet for the shortened sentence. If lengthened one should then shake their hands and then point to their mid section while saying the last two things.
