Ho-pourri

The combination of cheap perfumes that forms a putrid cloud of fragrences in the air, usually following groups of trashy club-goers.

"Oh, man. Get a load of this bunch coming at us! You think they're going to Whiskey Dick's to do jello shooters and try to get on Girls Gone Wild?! Oh my god, what's that smell?! I can't breathe! I *cough* CAN'T *cough* BREATHE!"

"Oh, yeah dude. That's the Ho-pourri cloud. It's what you get when you get a nice mix of cheap-ass knock-off perfumes."
