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.

Royal Flush

Going to the toilet to urinate after blowing a load to get rid of any excess semen.

Yo Mr. White I did a royal flush earlier and I almost ascended.
Wr. White: Jesse what the fuck are you talking about?

PINCH one FLUSH one

When doing time in any prison or county jail anywhere always remember and abide by the ‘Pinch One Flush One’ rule. The way this works: As soon as you ‘pinch one off’ HIT THAT BUTTON so your cellie doesn’t have to endure or power through your shit stink. Every time you pinch one, HIT THAT BUTTON! Actually just keep hitting that button on the first big pinch. Prison/Jail shitters usually have a ferociously powerful flush. You do your part and let the shitter do the rest. No one’s gonna jump all over you as long as you you hit that button. ALSO!!! Never use the shitter during meal times. Not sure about this? Fuck around and find out!

“Ugh! It smells like straight asshole up in here! Hey little homie, hasn’t anyone ever told you to PINCH ONE FLUSH ONE?

AND STAY HITTIN’ THAT BUTTON!!! SHIT!!!!!”

Boy Jim, your report was terrible. Next time you better not flush the mouse or we may have to let you go.

royal flush

A thing in poker when you have the king, queen, jack, ace, and 10 and they're the same suit (diamonds, spades, clubs, or hearts). It's one of the best hands you can get.

The chances of getting a royal flush when you play poker are extremely low.
