where the fuck are you where the rave scene is getting popular? wish i was there. ok, as a geriatric raver from the last decade to early 2000s lemme tell ya what went over real nice, because it'll still work.
pack your backpack with tons of flavors of gum.
however, your secret weapon will be pop rocks. need i say more? get as many girls to make out with you after you eat some pop rocks...word.
always carry lip gloss, a lighter, and menthol cigs, even if you don't smoke.
learn to give really good massages and offer them to girls. this is one area of 'rave game' where you might encounter the most rejection and maybe some angry boyfriends. i always thought the guys who did this were sleazy, but i also saw it work.
I used to buy glow sticks in non-traditional colors like orange, purple, red, and white. girls will come to you and want to use your glowsticks. invest in some kind of really cool, interesting LED thing.
show up as an integrated fashion statement. don't just be another one of those dudes with baggy pants and a visor. when i first saw him i thought Mystery was just some raver who had some show on vh1. anyone from the true underground probably knows what i mean.
if all else fails....show up with a bag of pills and you're golden.
all these points assume you're talking about real raves, where a lot more people are rolling than drunk.
