A slut bun is a hairstyle in which the girl's long hair is thrown up in a casual and loose bun on the very top of their head to create a bobbing huge bun that sticks strait up and wobbles. It is a somewhat sporty look, but it is usually done by the school slut who was too lazy to straiten or curl her hair that morning.

Along with the messy form of slut bun or skank bun a slut bun can also be a tight ballerina type bun that is located directly on top of the head, so that the head looks like the lid for a ceramic sugar holder.
