Rim Shitter 

To forego the toilet seat when one takes a dump. To park your ass on cold porcelain when defecating.

Toilet seats are for chicks, dude. I'm a Rim Shitter like a man should be!

rim flapper

The highly velocitized escape of gaseous matter via the rectum whereby the rim of the sphincter is first inadvertently puckered inward, then violently blown outward causing a momentary flapping as the blast escapes then subsides. The turbulent build up generally occurs as the sphincter is squeezed shut for extended periods. First dates, group meditations, and solemn religious ceremonies frequent such occurrences.

Damn that girl was so sweet I just wanted to sidle up closer, but for that bottled up rim flapper.

rim shot 

A musical term. A stroke in drumming where the stick is whipped down hard on the rim of the snare drum to give a resounding smack.

Man have you heard Cozy Powell play. Nobody can do a rim shot like him.

rim rider 

Happens after you clog a toilet with a serious dump. As the bowl overflows, there is one little floater that stays inside the bowl and rides around the rim as the water still swirls from the prior flush.

Dang, I just stopped up your toilet. At least you've got a rim rider cruising around to cheer you up!
