A far-below-average dude who is usually passed over in favor of more "succulent 'n' satisfying" male-meat by all but the most ugly/desperate/undesirable hussies who would otherwise have little chance of getting laid.
Economy-grade studs may not necessarily be dislikable guys per se, but they tend to be sorely lacking in the "hot 'n' heavy" department --- they may have low stamina in bed and/or perspire excessively during intercourse, only cum a weak dribble and/or have to wait several days to "recharge", have a small/narrow wee-wee, be very overweight and/or older than dirt, have an apathetic/lackluster personality, etc. Extra points if they are financially-solvent, though --- at least they won't mooch off the lady they're with at the moment, plus they may even be willing to assist HER with the cost of a few groceries and/or housewares.
