The Ridings Theory 

The theory that (regarding any upcoming physics test) you either know it or you don't. Not to be confused with the Ridings Postulate, which states that you either know it or you don't regarding ANY test, not simply physics. Applying these ideas often results in failure.

Me - "Dude, I have a physics test tomorrow! Fuck!"

Ridings - "Same. But I'm not studying, according to my theory, the Ridings Theory - in physics, you either know it, or you don't."

Riding the Pine

In team sports, players not actively participating in the game sit on the sidelines or "ride the pine" until the coach puts them in the game.

Even though he was drafted in the first round, he'll probably be riding the pine for a few games before they start him.

Riding the Flamingo 

Riding the Flamingo is when; one moment you are innocently admiring the Flamingo's in the park, the next, your pants are down around your ankles and you find yourself balls deep in pink fluff.

I saw Ross in the park yesterday, he was riding the Flamingo, and it was savage.
