Sean's Fundamental Law of Rock Skipping 

The theory that, any rock, no matter the shape or size, can still skip a considerable distance upon a body of water if spun fast enough. This theory disproves that a rock HAS to be flat in order to skip upon water.

NOTE: This theory was in fact proven through vigorous testing during a boring afternoon near a lake.

Kid: "Hey, that rock is squarish. It wont skip on the lake. You need to find a flat one."

Friend: "No, it should skip. Sean's Fundamental Law of Rock Skipping disproves that myth."

Kid: "It doesn't have to be flat?"

Friend: "Nope"

Skipping Rocks 

When you take a dump that feels like a good one but instead shoot out tiny pebbles that are unsatisfactory and usually splash up and leave your bottom wet. A benefit of this is that you will most likely be left with a 'rock bottom' that is a no mess no fuss clean up with little to no toilet paper usage.

I.e. : I was gonna lay some cable but instead wound up skipping rocks when I got home, but at least it was a one wiper.

skipping rocks 

The ability to pitch / skip flat stones /rocks across water. It's kind of a game to see how many skips one person can get as compared to someone else skipping rocks.

When you and I were kids we were always skipping rocks on Silver lake, I usually won.
