Gravity's favorite trick on a face, pulling it toward a bad mood.

means To draw the eyebrows down and together in displeasure, concentration, or worry — the facial shorthand for 'not pleased.'

from Frown entered English from Old French froignier, meaning to curl the lips or snort disdainfully, which traces back to froigne, a word for a surly or sullen expression — possibly related to Gaulish roots tied to nostrils or facial grimacing. By the time it settled into English, it had narrowed from a whole disdainful face to that one tell-tale wrinkle of the brow.
