Let’s see. This is not a trick question, but it is a concern which some Team Leaders should assess when building rapport and especially when mentoring new hires and promotable employees. What does going bananas mean?
The term bananas first appeared in the US in 1942 “The American Thesaurus of Slang: a complete reference book of colloquial speech in the definition for eccentric” with a meaning of: “Balmy, bats, bent, crazy . . .” In 1833 an American slang meaning of the term bentwas to be interpreted as intoxicated with alcohol or drugs. So, this just a definition using slang to define other slang.
