Babel effect
When one tiny thing gets turned into a million different things by different people, all thinking they’re the smartest person in the room. You can still tell it came from the same place, but only if you’re drunk or high.
A single phrase: 'I love pizza.' Turns into a 500-page thesis on pizza, a pizza-shaped hat, and a man who eats pizza for breakfast, lunch, and dinner.
A DM that says, 'Hey, wanna hang out?' Ends up being a 3-hour debate on the meaning of 'hang out' and whether socks count as clothing.
A meme about 'the best way to eat a donut' leads to a full-blown donut war, a donut-shaped sword, and a donut-shaped dragon.
