I have never given much thought to 'taking a slash' as we say back in the old country. With retrospect I am always amused by the various terms used to describe the function. Such as 'Shaking the hand of the wife's best friend' , 'Pointing Percy at the porcelain' , 'Syphoning the python' or 'Milking the maggot' are a few that spring to mind. I have always and for some inexplicable reason been more amused by breaking wind!
