Speedball is a kind of cocktail made from one part vitamins, one part marijuana, and a dash of Angostura bitters.
The mixture is made in a custom toilet that can only be found on the West Coast of the East Indian Ocean. A speedball like substance can be made in normal toilets, but it won't have the offical designation "speedball."
Its effects include numbness of the tongue and ankles, and feelings of mild schadenfreude.
It is sometimes used medically to relieve the hangovers that can be caused by excessive use of LSD, and as a general pick-me-up.
Though generally safe in small doses, speedball can be habit-forming. Oscar Wilde and River Phoenix have both been claimed to be addicts, and Karl Marx once suffered an overdose of the stuff ( coincidentally, while gang-raping Tamia ), William Butler Yeats also overdosed on it, just not gang-raping Oscar Wilde, in his case, pigs. River Phoenix frequently holds seminars claiming speedballs can easily kill. He even claims they killed him and possibly Nietzsche, however, his claims are often dismissed as being from a dead man, which they are.
