A steel barrel with combustible material inside. Usually lit during cold winters by bums in urban areas to keep warm. You can see these Bum Warmers in alleyways, under bridges, and on sidewalks. Usually the said barrel is surrounded by several bums and homeless trying to stave off the cold.
Bum1: Begging for change is sure hard work. Lets go find something to keep us warm

Bum2: I know of a good alleyway with a nice cozy Bum Warmer
