Some stand in the corner and bob their heads, some mong out in the middle of floor, but a lot rave till 6am and still want more. 
Find these guys anywhere with a DJ and space to skank. At nights playing anything from house, hardcore, electronica, drum and bass, dubstep the list goes on.
It all started with the acid house scene in the 1980's , in the 90's moved on to probably most ravers favourite: Juuungle, with the start of illegal raves. 
Nowadays all ravers music can be found at one event but In different rooms. Quite a few main city's across the country  have a strong scene, but London's still probably the place with clubs like Fabric, Cable and Corsica Studios. 
The style is pretty mixed, it can be anything from fluorescent, skimpy, fury, shiny, colourful, undeniably tacky tutu's and bikinis.. to checked shirts and chinos, of course a touch of glow paint to add the 'rave' effect.
