Whore Juice
Any cheap, overpowering and especially cloying perfume.  Generally favored by insecure tarts that, cat-like, want to make sure they "mark" their territory.
Dammit, the  broad next to me on the train was friggin drenched in whore juice -- I'm gonna catch hell when I get home!

I HATE taking the Staten Island Ferry -- it always smells like whore juice!!
