porcelain percussion

Porcelain Percussion is the bass sound heard outside a bathroom when the occupant is involved in a rear-end explosion. This event usually results in having to clean the bowl before exiting the facilities.

Cathy: Damn Bob, that was some serious Porcelain Percussion!! It almost smells as bad as my fold jam.

Bob: Thanks...if you would have done that, your toilet muffin would have slapped you in the head.

painting porcelain

the act of defecating on such a large scale that the interior of a normally white porcelain toilet bowl is rendered an entirely different color, typically brown

"Jim, where are you headed off to in such a hurry?"
"I don't think that oyster burrito agreed with me. I'm pretty sure it's gonna have me painting porcelain."

Porcelain Drips

Taking a shit but only burning drops of liquid feces are expelled. They sting the sphincter so bad that you grab the handicap bars, grimace with pain, clench your teeth and wish someone would shove an ice cube up your ass just to cool it down. If you didn't know better, you'd think hot lava was pouring from your bung.

Carl partied all night and then made a trip to Taco Hell. He suffered the next morning with the porcelain drips.

Porcelain Bus

Name given to the toilet when vomiting, used in reference to holding the seat while spewing in the same manner as you would hold a bus steering wheel. Not to be confused with the porcelain pony as quoted above

Shit, I had a few too many jagers, I think i may need to drive the porcelain bus

STAIN THE PORCELAIN

to take a dump; drop a deuce; pinch a loaf; drop the Cosby kids off at the pool.

Man, did I ever stain the porcelain when I woke up this morning!

Porcelain Cowboy

Banging a girl from behind while she vomits into a toilet. Best used when said girl is completely hammered.

I gave Cally the Porcelain Cowboy last night. She was so trashed. I was like 'Yippee Ki-ah mother fucker! *smack*'
