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"

slippering 

A type of spanking that consists of hitting the buttocks with a shoe -- or "slipper." It used to be a common form of corporal punishment.

My daddy was so upset at my mistake that he took off his shoe and gave me a slippering on the spot.

Skipping the flump

When you do something socially unacceptable because you forget that there are people around. This is anything dumb that you would only do when you're alone, except you do it in public for everyone to point and laugh at you.

Scratching your balls in public is an example of skipping the flump

Person 1: Dude, stop scratching your balls in public
Person 2: Sorry, i just skipped the flump
