Snaggleberry:Homeless scavenger. The kind of person you see walking down the street with a shopping cart, three coats, and bags tied with rope and then tied to his arm. They sleep in boxes or with newspapers behind grocery stores and occasionally fall asleep in the store during winter. Snaggleberries
