A pure form of MDMA (ecstasy), also known by the slang term "Molly". It comes in powder form usually white, but sometimes yellowish or pinkish in color. A very popular drug at music festivals hence the name. Not to be confused with "Hippy Crack".
Steve took 2 tenths of some good hippy blow and has been rolling balls all night.
