Origin: "Bananas" meaning crazy is documented by 1968, though the word had already carried a narrower underworld slang sense of "sexually perverted" since 1935. The most credible theory, from lexicographer J. E. Lighter, ties it to the earlier, related phrase "go ape" — apes and monkeys have long been associated with wild, unrestrained behavior in popular imagination, and bananas are their most iconic food, making "go bananas" a natural fruit-based cousin of the ape idiom rather than an independent invention. Several other, considerably shakier theories circulate as well, including ones built on the fruit's curved shape or on various supposed erotic connotations, but none carries anything close to the evidence behind the ape connection.
