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.
"There are so many shmankers hanging out at the public library i'm afraid to let my kids study there"
the act of removing a marijuana bud from its stem. After a marijuana plant has had all the excess leaf removed (called trimming or manicuring, etc) the plant at some point in the process needs to have the bud removed from the stem, this is called bucking. this may be derived from the logging industry where bucking refers to cutting a log into lengths for transport or rounds for firewood.
"All my trimmers took off to work for my neighbor before i had a chance for them to buck it all. Now i gotta do it all myself"
