What is plate glitching and how I can use it?

What is the plate glitch in skyrim and what can I use it for? How and where can I use it? How can I use it to get through things as I have heard it can help me do so.

The plate glitch is done by grabbing (not picking up) a plate, and lining yourself up with it and running at a wall. This can cause you to go through the wall. You can use it to go through a lot of walls, though Riften seems to be the best place to practice it. Some uses of it would be going through walls to avoid locked doors, or escaping the map to explore other areas. Corners of walls are sometimes easier than other parts of the wall.
