Eating greedily or in large amounts until very full, or a narrow rocky valley through which a river flows.
From Old French 'gorge' meaning 'throat' or 'mouth,' from Latin 'gurga' relating to whirlpools and gulping. The eating sense evolved from the idea of filling the throat.
The word 'gorge' has two completely different meanings—one about eating and one about geography—yet both come from the image of something being swallowed or passing through a narrow opening!
