psychedelic

A more formal term originally used to describe something that seems inspired by a mind-altering drug, or the effects of the drug itself. Drugs classified as "psychedelic" include marijuana and LSD.

More commonly now, since the age of psychedelia ended in the early-70s, the term is used solely to describe things that seem inspired by or seem to replicate the experience of mind-altering drugs. The term is most often applied to art that utilizes bright colours and bizarre patterns or music that uses strange, non-standard timing signatures, keys, chords, and the like. The term is somewhat synonymous with trippy.
