Definition

   • A slang term for the hallucinogenic drug LSD (lysergic acid diethylamide): This term originated from the title of a 1967 song by The Beatles. It functions as a street name or code name for the drug, often used to refer to it in a covert or culturally referential manner.

Usage Examples
