A slut is someone, usually a woman, who’s stepped outside of the very narrow lane that good girls are supposed to stay within. Sluts are loud. We’re messy. We don’t behave. In fact, the original definition of “slut” meant “untidy woman.” But since we live in a world that relies on women to be tidy in all ways, to be quiet and obedient and agreeable and available (but never aggressive), those of us who color outside of the lines get called sluts. And that word is meant to keep us in line.
