My search for “hunky” came back with 2 citations including only a slightly longer word “chunky”. For the record the only offering of this catchword to date follows:
Hunky (adj) is an abbreviated form of “hunky dory” and is more often than not masculine since it includes the term “hunk” meaning a healthy, attractive adult man. It is often used in response to questions such as “how are you?”, “how are things”, “Doing alright?”, etc. It might also be used in a sentence such as “I was walking downtown and I’m feeling pretty hunky.”
