I hate them. I really fucking HATEHATEHATEHATEHATE them. I hate the deafening crappy music that you can't even dance to. I hate the seizure-inducing or non-existent lighting. I hate the overpriced booze. I hate the vacuous, obnoxious narcissism surrounding me from every direction... closing in on me, everywhere, like a death trap, can't breathe... sweat and booze breath and cologne and perfume and drugs. I hate the obnoxious drunks. I hate having to get gussied up and wear expensive clothes so that I can get inside the damn place, only to be drenched in sweat and the residue from other people being all up in my business. I hate fearing that I may get mugged on the way home.
I've been to a handful of nice, low-key ones or ones that are essentially nightly raves, and I liked the hippie, psychedelic feel of them... but the majority are just not enjoyable places to me.
