Internecine

pronounced IN-ter-NEE-sin. It comes from the Latin: "inter" (between, among) and "necare" (to kill). It means a conflict destructive to both sides, or very bloody. We do tend to use it to describe civil wars.

When one or more women derides another woman or group of women for not following a (often meaningless) social convention, generally motivated by obvious jealousy or an unwillingness to see someone of their own minority group get ahead. This is similar to the "crabs in a bucket" phenomenon where crabs will damage one another in order to be the last one killed.
