Drookit is a Scots person’s way of saying they’re soaked to the skin or drenched. We get enough rain in Scotland that it’s a fairly regular occurrence.
In Scotland it’s a common experience to be drookit. It’s not just the rain and snow, but the wind driving it at you horizontally, that surprises visitors and new Scots. It can be a lovely summer’s day one minute and bucketing down with rain the next, so you always have to be prepared for getting drookit, or more sensibly avoiding getting drookit.
