When a poorboy pads his wallet with $1 bills and $5 bills, then puts larger bills on either end of the cash wad to impress friends or girls or strippers, fool them and make them think he's got lots of big bills. This is called a Poorboy Roll.
One stripper to another: Did you see how thick his wallet was?
Other stripper: No, it's a poorboy roll, once the 20's are gone, you'll see he just has 1's and 5's.
A strange awkward little man, who is severly lacking is social skills. Has an affinity for robots and ninjas, maybe even as a lover. Has bowel problems and lovingly talks to his turds as they are flushed. Caution! He has the capability to become extremely violent if provoked.
