Rave? Used to be a competent newspaper would define the terms used by an insignificant, fringe subculture.
Officially it’s just a style of entertainment with lights and music. Unofficially it lends itself to being spiced up with drugs.
From my understand, it mixes loud, bassy electronic music with fairly baggy pants (actually not jeans), and a loooooot of glow sticks. It’s almost its own dance style.
