Term for a slightly less-than-average person only accepted by his peers because he/she boosts their self-esteem due to their ignorance or lack of intelligence. Also begs others to the extremities of their nerves for money/materials. Can be used as a nick-name or noun/pronoun.
Joe:hey Jackson, got any money i spent all mine on gummy bears & weed.
Jackson:(speaking to Walt). Gosh he really makes me mad hes such a Jew.
Walt: Yea he's such a Joe Blow.
Generic term for "the average guy." The "man on the street," so to speak. Sometimes lengthened to "Joe Blow from Kokomo" (after Kokomo, Indiana).
As far as Joe Blow is concerned, the worst thing about the Iraq War is inflated gasoline prices.
