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"
