witch's were once imagined as old hags with
wrinkly skin and icy blood. ha! So the phrase "...colder than a witch's tits..." was used during very
cold weather. When someone who still thinks this way came into a warm house or room, often, the phrase would
come to mind.
Ol' Harry came into the cabin
wrapped up in almost
everything he had. The blizzard was just
reaching it's peak. He said shiveringly, "DDDDamn! It's ccccolder than a witch's tits out thththere!"
