Colloquialisms come in many forms; some are regional, some would only be understood due to shared experiences and some exist solely within the family group. My grandparents, who lived through the rationing of WWII, when making a sandwich, used to say " Make it bread and scrape." This meant putting butter, margarine or jam on the bread and then scraping off as much as you possibly could to make it go further. Another, peculiar to Glasgow I believe, is "Well, I'll go to the foot of our stairs!" Meaning something sufficiently interesting is happening in the street to entice you downstairs from your tenement block to see what's going on. Anyone else got some they'd like to share?
