A term used to describe one person viewing another person's profile on facebook, or various other social networking sites, usually in excessive amounts. This term seems to be derived from "Facebook Stalking". It can also be used to describe someone watching or stalking someone else in real life. In this situation, one may be deemed a "creeper".
