The 'Wicked Witch of the East Bro' meme originates from a viral 2018 video featuring two friends, Matt and Nick, engaged in an absurdly heated argument about 'The Wizard of Oz'. The conflict centers on a factual error regarding which witch arrived in a bubble, leading to Matt's explosive and iconic line: 'Wicked Witch of the East, bro!' The meme perfectly captures the frustration of dealing with someone who is confidently incorrect about trivial facts. It is widely used to mock pedantic arguments, fandom gatekeeping, or any situation where a minor disagreement escalates into a passionate, screaming match.
