Bonercoaster 

When you see a really hot guy or girl, but then something very significant quickly changes your opinion But then another aspect picks up, just to be Disappointed again

So I was on the bus the other day, and tere was this super hot chick sitting across from me, but then she lifted her arms and damn her pits were hairier then mine. But she had no bra and a super loose singlet and it was not that bad. Until she kissed her girlfriend. Man that was a real bonercoaster

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."
