The Canadian equivalent of the american term, [punk]. A word used in the Canadian prison system to describe informers, molestors, child killers and all inmates segregated from the general population in protective custody. In a looser sense, anyone who has become hated by the prison population in general for suspect behaviour, or irritating behaviour may be thought of as a goof.
To be called a goof, espescially if not true must be met by instant violence or you will lose all respect formerly given to you. If this isnt done, or you are incapable of defending yourself you may as well check in. (ask to be moved to [P.C.], protective custody)
