A combination of psilocybin and a sybian, it is a sybian in which the fallic end is shaped more like a Psilocybin mushroom and is coated with the mushroom powder and flakes, causing intense spiritual tripping while being vibrated by a machine to an orgasm.
Lucinda nearly freaked out when she was on that psilosybian yesterday, she had the voltage all the way up, and I reckon there was a lot of powder on that thing, what a trainwreck that whore is.
