For those that are curious about this image... 'ravers' consume the drug ectasy (amongst other drugs) and to prevent injury to their teeth, due to the drugs effect, and to aid in producing saliva, use pacifiers.

ravers- dancers, more than likely under the influence of drugs (that's kind of the point or excuse to dance / rave- use drugs)

a rave- a gathering of like minded youth, many fueled by drugs, dancing for hours on end to techno music (fast beat, synthesized music) tribal atmosphere

ecstasy- an illicit drug, causes most users to gnash their teeth obsessively, and dries out the users mouth

Notice the raver in the background- a pacifier is being used.

You forgot to mention that a slang for tripping on X is called "rolling".
