green around the gills

Meaning: Sick to one's stomach; nauseated.

Example: “After the boat ride, he looked a little green around the gills.”

Origin: Two older pieces combine here: green has stood for a sickly, nauseated complexion in English since around 1300, and "gills" was already informal slang for the loose flesh around the jaw and lower face by the 1600s — borrowed from the fish part by simple visual analogy, the way a person's neck and jawline flare out below the ears the way gills flare below a fish's head. "Green about the gills" for looking ill is on record from 1628, with the now-more-common "around" variant settling in by around 1800. Its likeliest home was shipboard, describing the pale, queasy look of a seasick passenger — a face that has quite literally gone the wrong color.
