Top Definition
The combination of LSD and psychedelic Mushrooms taken in one setting.
A friend of yours is tripping. They are "Candy Flipping", or rolling on MDMA combined with LSD. A second friend of yours is "Hippy Flipping", which is a combination of Magic or psychedelic Mushrooms and MDMA. You, on the other hand, are "Lucy Booming", which would be LSD and psychedelic mushrooms taken at one time.
