Having a face that is long and narrow like a violin; or describing someone with a foolish or silly expression.
Compound of 'fiddle' (violin) and 'faced' (having a certain face shape). Could reference either literal facial geometry or be used mockingly of silly-looking people.
Before 'fiddlefaced' existed, people noticed that some faces were genuinely violin-shaped, and before medical imaging, creative compound words like this helped people describe human variation humorously.
