Mercy Flush

Flushing a particularaly bad-smelling turd down the toilet in the stall of a public bathroom while you are still crapping so other people will not smell it. This can be repeated as many times as necessary.

Person in right stall: *Poops*

Person in left stall: "Oh God! That's Horrible! How about a
Mercy Flush?"

Person in right stall: *Flushes*

Person in left stall: "Thanks."

Person in right stall: "Welcome" *Continues Pooping*

Mercy flush

Flushing the toilet, as not to clog it if your taking a big crap

-- Used if you are taking such a big crap that it might clog the toilet, so you flush 1/2 way.

Man, give that thing a mercy flush, so it wont overflow!

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!"
