Dishonorable, disreputable, or behaving in an ungentlemanly or unkind way.
From 'cad' (a man who behaves dishonorably) plus the suffix '-ish.' The word emerged in 19th-century British English to criticize ungentlemanly conduct.
The word 'caddish' became popular in Victorian England when strict social codes meant abandoning a woman was scandalous—it was the ultimate insult to a man's character!
