A sex act consisting of two or more consenting adults, one of whom is anally penetrated by a large fruit based object (usually a pineapple) dipped in hallucinogenic narcotics that results in a major spiritual evolution and/or a fusion of the participants souls. The penetration causes a euphoric sensation that can last for hours or randomly spawn for up to a week.
Incorrect insertion can cause a major jerk of anal muscles and can result in a massive muscle tear. Chemical reactions are not unheard of and side effects include delusions of grandeur, feelings of persecution, feelings of religious confusion, and massive anal leakage or hemorrhaging.
