A to Z of Zowie (Hippy Slang)

Found in an old Sunday Observer colour supplement from December 1967 this glossary of (then) very recent hippy and 'underground' slang, apparently known as 'Zowie.' In Britain 'Zowie' is mostly associated with David Bowie's son Zowie Bowie (born 1971) now known as Duncan Jones...For a comprehensive online dictionary of hippy slang check out Skip Stone's Hippy Glossary. Since the Summer of Love some of the words below have entered the language (groovy, happening, trip, vibrations, riff) and some like 'Zowie' itself and 'grey' have had very little currency. Slang authority Eric Partridge imported most of Peter Fryer's glossary into later editions of his Dictionary of Slang and Unconventional English.
