In just four short lines, Dave Bonta captures the awkwardness of feeling out of place at a social gathering. The speaker goes "out in society" and turns himself into "a crow's sandwich among the ladies." It's a strange, funny image, and it takes a moment to untangle. A crow's sandwich is presumably something a crow would eat, so the speaker seems to be offering himself up as scraps, a dark, scruffy bird's meal set down among the refined company around him. The title, "On the make," usually means hustling for advantage or attention, which adds a wry twist: he is trying to make an impression, yet the result isself-mockery.
The speaker sounds self-conscious and a little rueful, but not wallowing. The humor keeps things light, though there's an edge of discomfort underneath. The mood is wry, quick and slightly unsettled, like a joke you tell about yourself before anyone else can.
