(Variations: spit in the wind or dry spit on a hot day may replace a bucket of warm spit) Of very little value; worthless: The new telephones are not worth a bucket of warm spit/ a cable TV contract for the Bronx, Brooklyn, Queens, and Staten Island that's worth about as much as a bucket of warm spit/ Some is good. Really worthwhile. But a lot of it ain't worth spit in the wind/ In the great scheme of things, woodchucks are not worth dry spit on a hot day (1970s+)
