A shmanker is low class, white trash, usually tweeker, often wearing flannel and having mustache or goatee. Shmankers can be found on the streets often riding a cheap or stolen bicycle. They are often semi-homeless to fully homeless and usually are couch surfing or holed up in the seedyest of motels. They are often the at the bottom of the crystal meth distribution pyramid and are in and out of prison.
