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.”

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

Yellow Jacket

the wasps that fly around garbage, follow you around and buzz in your face for at least 5 minutes, fly into your car window and make you almost shit yorself, and sting you just for fun because theyre assholes. these fuckers are nasty, and look orange at a distance and hover in circles around wherever they are, and if you get near them, they will fuck with you until you can wave them off without getting stung. they also like flying into peoples houses. fortunately, they are easier to kill than flies, but are still annoying as hell, and can even be scary, especially when youre driving a car, and they fly into your window and start flying around in front of your face or land on your junk, recipies for disaster.

there was a giant wreck tying up traffic on the highway. some dude had his window open. a yellow jacket flew in, and stung the guy in the face, then he slammed into another car, and ther traffic behind them piled up and nailed them.

yellow bomb

Yellow Bomb: a gallon size plastic jug, such as once contained milk or water, now used as a urinal by truckers and other vehicle drivers and passengers to avoid travel delays at conventional rest stops. Yellow bombs can be utilized by men and boys with just a single hand to manipulate a penile insertion into the neck of the container. Women and girls can accomplish the same final outcome, but may require some practice to acquire the skill necessary to avoid spillage or overspray, may require two hands to simultaneously hold up the container and hold back garments, and may require a funnel like appliance (commercially available) to direct their stream. Very young children typically need a more mature helper to hold the yellow bomb in the appropriate position in relation to the relevant genitalia. As the container becomes filled with urine, it takes on the yellowish appearance of its contents. As the filled container is thrown out of a moving vehicle, it may explode upon impact with the roadside. This likely explains the origin of the name, yellow bomb. The more environmentally conscious users of yellow bombs do not discard them at roadside; rather, they empty the contents onto mother earth and recycle or continue to use the container.

1) "Daddy, I can't pinch it anymore; I've GOT to GO!" "OK, Son, just grab the yellow bomb out of the back seat and let it flow."
2) "Damn it! I was walkin' down the highway, mindin' my own freakin' business, and some asshole truck driver pitched his yellow bomb out his window. It burst right in front of me and gave me a smelly golden shower. YUCK!"
3) "Sorry, Honey, but our maladroit little daughter just spilled the yellow bomb all over our back seat."
