Crasterbate

To cry while masturbating.

After that one kid walked in on me banging his girlfriend, he sat down and crasterbated in the room while we got stuffy.

the coaster

Snorting a mixed line of oxycontin and cocaine, that you setup before you passed out, as soon as you wake up in the morning.

Me: Hey you seem pretty relaxed this morning
You: Yeaaaaaah brah, I woke up and rode the coaster this morning.
Me: I think your nose is bleeding....
You: Riiiiiiiiight on.

Boner Coaster

This is the phenomenon that occurs when you see a ridicuously hot chick that makes you instantaneously pop wood, blow your load, pop wood, blow your load, pop wood, and so on. Similiar to the peaks and valleys one would experience on a roller coaster.

"Dude, you see that chick in the mini-skirt? I'm totally riding a boner coaster right now."
