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

get flushed down a toilet and come out in a new suit

1. A person who "looks" wealthy, acts wealthy and most people think he is wealthy but in reality it's all pretend.

2. A person who "looks good" no matter what they do. They come out on the winning end all the time.

He's so smooth and such a player he could get flushed down a toilet and come out in a new suit!

trinity flush

The flush that follows after you ejaculate into the toilet (or into a tissue and then throw it into the toilet) and follow up immediately by sitting down, pissing and taking a shit

I was horny and I needed the toilet so I just did a 3in1 and followed up with a trinity flush

Courtesy Flush

Courtesy Flush: When you are with someone in a tight space or tight hotel room or on a bus or a plane, it's a courtesy to flush when the tip of the brown torpedo hits the water.

If you have to do a #2, can you please grant me a Courtesy Flush or a few courtesy flushes.
