A Fozzy
A fozzy is a hairy, smelly person who lives on the streets and eats expired food out of a trash can.
That fozzy I saw on the bus smelled like he had been in a dumpster for a month.
My friend's fozzy brother once tried to eat a pizza that had been left in a rain puddle for three days.
That fozzy once tried to sell me a sandwich that looked like it had been touched by a raccoon.
