A sexual deviation of Psychadelic. It means pretty much the same as bootilicious. The difference being that shaggadelic is not specific to any meaning, and that it is never EVER used.

*note: If visiting Britain, do not great people with this phrase. Doing so will result in yourself being ostracized. Austin Powers does not represent 60's Britain.
yeah baby, shaggadelic!
