Mercy Flush

The extra flush that comes between wiping and dumping, used when the shit is unusually large to prevent a plug of soggy TP and feces forming in the pipes.

"Shit guys, I took the biggest crap yesterday, I had to mercy flush so the toilet wouldn't plug!"

Sex flush

1. When your body reddens during an orgasm and shortly after it. You'll see red spots & striped all over your stomach and chest area.

2. Less popularly used to a woman when she gushes out massive amount of squirt during her climax. Just like how a toilet flushes water.

I was fucked so good where I flushed heaps amount of squirt from my pussy!

My body has been sex flushed! Look at the red stripes all over me.

Riddle Flush

When engineering students at Embry-Riddle don't actually learn the material; they just retain it long enough to pass the exams and get the grade, then proceed to purge it from their brain. Thus they go into the field with a degree, but actually know nothing.

"Bro, help me with this whack-ass integration." "What, is that Calc 2? I used the Riddle Flush and forgot that shit after freshman year, homie."

courtesy flush

When you're in a public restroom, going number 2, flushing the toilet while you're still using it to lessen the odor and as a neighborly gesture.

Yo dude, give me a courtesy flush........you're making this bathroom rank.

In poker, the second best flush possible given the situation.

caution flush

When you've taken such a massive dump that if you don't flush before you wipe your ass, you'll probably overflow the toilet
(similar to the courtesy flush)

Oh my god, I was so embarassed when I nearly overflowed my new boyfriends' toilet.
You should have used a caution flush

Uterine Flush

The female period. On the rag. Aunt Flo. Monthly bill.

Rachel has the uterine flush so won’t be getting any tonight.

Her uterine flush was leaking through her maxi into her new white jeans.
