A Theory Made up by Barney Stinson (How I Met Your Mother) stating that there is a chain/cycle of screaming in which one (original screamer) yells at someone else, then that person yells at another person and another and another, so on and so forth. This chain/cycle will eventually lead back to the original screamer, ending the Chain of Screaming. AKA The Circle of Screaming or The Pyramid of Screaming.
