1620s, earlier raspis berry (1540s), possibly from raspise "a sweet rose-colored wine" (mid-15c.), from Anglo-Latin vinum raspeys, origin uncertain, as is the connection between this and Old French raspe, Medieval Latin raspecia, raspeium, also meaning "raspberry." One suggestion is via Old Walloon raspoie "thicket," of Germanic origin. Meaning "rude sound" (1890) is shortening of raspberry tart, rhyming slang for fart.
