A phrase originating from the lower half of Scotland, devised by a comedic genius hailing from the sunny schemes of Ayrshire. Shitebaggy is a phrase used to describe an action or the way a person is acting, it is often used when the person in question is seen to be acting in a low manner or if they are scared of something.
"Sam's just whiteyed all over the gaff" "that's well shitebaggy"
( people) in general need to be taught and shown the worth of basic decency and respect for others of their kin. It manifests in each individual differently. This phenomenon I would refer to as 'being a shitebag' is applicable to anyone, even and especially the best of us. So long as we remain aware of, and understand the implications of shitebagginess, we might all remember to quit being a c**t every now and then.
