scrounge

1915, alteration of dialectal scrunge ("to search stealthily, rummage, pilfer") (1909), of uncertain origin, perhaps from dialectal scringe ("to pry about"); or perhaps related to scrouge, scrooge ("push, jostle") (1755, also Cockney slang for "a crowd"), probably suggestive of screw, squeeze. Popularized by the military in World War I.
