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.
Example: Arthur’s boss’s boss screams at Arthur’s boss, Arthur’s boss screams at Arthur, Arthur screams at Marshall, Marshall goes home and screams at his wife,
Lily,
Lily (a kindergarten teacher) screams at one of the kids in her kindergarten class (hmm, let’s say Mary), and then Mary goes home and screams at her
dad, Arthur’s boss’s boss, thus ending The Chain of Screaming.
