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
