Yellow-Blue-Brown Alliance

The informal alliance of Liberals (Yellow), Conservatives (Blue), and the Far-Right (Brown) in certain political contexts, where these normally opposed groups align on specific issues—typically against common enemies: progressive left movements, anti-colonial struggles, or challenges to the established order. The alliance is not formal or acknowledged; it's emergent, visible in voting patterns, media coverage, and online discourse where these groups suddenly sing from the same sheet. The Yellow-Blue-Brown Alliance explains why liberal outlets sometimes echo far-right talking points, why conservatives suddenly sound like libertarians, and why otherwise opposed groups converge on certain targets. It's politics as "the enemy of my enemy is my friend," even when the friend is usually an enemy.

Example: "On the issue of protests against corporate power, the Yellow-Blue-Brown Alliance emerged: liberals criticized the 'tactics,' conservatives condemned the 'lawlessness,' and far-right commentators called it 'proof of communist infiltration.' Three normally warring groups, united in opposition. The alliance was temporary, unspoken, and effective—the protest movement was drowned in cross-party condemnation."

If it's yellow, let it mellow. If it's brown, flush it down

A phrase used to determine the appropriate circumstances under which to flush a toilet. Urine was to be left unflushed in the toilet bowl while feces were to be flushed right after bowel evacuation. This was used in efforts of water conservation either in the sense of environmental conservation or the saving of clean toilet tank water during power outages in remote areas.

“Man, don’t waste three gallons of water to get rid of a cup of sterile piss.”
“Why is that kindly hippy?”
“Just remember man, 'If it’s yellow, let it mellow. If it’s brown flush it down.'”
“Thank you, sir. Perhaps with the water we save in the crapper you might be able to bathe more thoroughly in the future.”
