SCP stands for Secure Containment Procedures or Special Containment Procedures, depending on the context. In the context of the SCP Foundation, SCP refers to anomalous objects, entities, or phenomena that require containment to prevent harm to the public or the Foundation.

The SCP Foundation is a collaborative online fiction project that revolves around a fictional organization called the SCP Foundation. The Foundation is a secretive organization that specializes in containing and studying anomalous objects, entities, and phenomena that defy scientific explanation. SCPs can range from seemingly harmless objects to world-ending threats.

SCP entries are written in a standardized format that includes a brief description of the SCP, its containment procedures, and any known or suspected effects it may have. The entries are often written in a clinical and scientific tone to emphasize the seriousness of the Foundation's work.

Some popular examples of SCPs include SCP-173, a statue that can only move when it's not being observed; SCP-096, a humanoid creature that becomes violent when it's seen; and SCP-999, a friendly and harmless blob that brings joy to anyone who interacts with it.

The SCP Foundation has gained a large following online, with a dedicated fanbase that creates fan art, fan fiction, and other content inspired by the SCPs. The project has also spawned several video games, including SCP: Containment Breach and SCP: Secret Laboratory.

It's important to note that the SCP Foundation is a work of fiction and should not be taken as real. However, the project's popularity has led to some confusion and misinformation online, with some people believing that the Foundation is a real organization.
