A small, impertinent person; a young dandy or a small, vain man (an archaic or insulting term).
From dandy + prat (British slang for a foolish or contemptible person). This 16th-17th century compound word was used to mock young men who thought they were fashionable but were actually seen as insignificant or ridiculous.
Dandiprat is a perfect insult from the age of Shakespeare—it combines fashion mockery with 'prat' (still slang for a fool in British English). It shows how people have always mocked those obsessed with appearance, using creative compound words to express their contempt.
