Practice popular at raves of taking ecstasty and LSD simultaneously. (A British band, Candy Flip, popular in the 1990s, was named after this practice).
It looks like EVERYONE here, except the cops at the doorway handing out water, did a candyflip.
A drug cocktail of acid and ecstasy. Taking both together intensify the effects of both substances, so someone who candyflips usually does a small amount of each for safety and to avoid too much for the mind to handle. In no way is candy flipping guaranteed to be safe, but some people do it to find out what it's like, usually younger people do this combination and some call it an incredible time, others of course have a really bad time, as common sense would suggest, using process of elimination.
The other night a group of people must have been on a candyflip. I don't think they were capable of a conversation and may not be for some time.
