Prop Clipping is a Glitch in which a physics prop gets stuck inside of the player. The glitch allows the player to Save/Load buffer into brushes, props, or OoB space.

How to

Pick up a prop, then walk into a wall. If you continue pressing yourself into the prop, the prop will usually clip into you. Once you are stuck you can Save/Load buffer down into the brush, prop, or OoB space below you. Alternatively, you can get the prop stuck in between two props so that it loses its collision for a short period of time. Then you can simply walk into it and wait until it regains collision.
