Old English word for a freak or side show performer, i.e. a person who would bite the heads off of animals as public entertainment. More recently used a highly offensive prison and urban slang word translating into 'pedophile' or 'sexual deviant'. Offending 'goofs' are isolated in prison and outcasts in public for fears of being assualted or killed. This would be in a criminology context however. 'Goof' can be used as a harmless noun or verb if the intention of the underground meaning of the word is unknown i.e 'stop goofing around'. In most inner cities in the United States and Canada the word 'goof' would be interpreted as a serious insult i.e. 'fighting words'.

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 isn't done, or you are incapable of defending yourself you may as well "check in." (ask to be moved to P.C., protective custody)
" You'd better check in dude, that guy called you a goof and you didn't answer." "That was a big mistake, even if you had ended up taking a beating it would have been better than doing your bit in p.c. with all those goof rats, skinners and kiddy diddlers." "Oh yeah, by the way, don't talk to me anymore. I don't want to be seen talking to a goof from p.c."

Goof is a street definition, for an individul that cannot be trusted, and his/her word means nothing. A Goof lacks solidarity, integrity, loyality and honour. A goof at any given time will cut your throat and sell you out to serve himself.
That Mark guy is a goof and can't be trusted. Mark is a rat fink goof, for he told the cops that I was involved in a crime.

The word goof means your basiaclly every bad word in the book. You have done wrong. Once your labelled as a goof, your better off relocating to a new city, it might be so bad, you might as well move right out of the counrty.
I can't believe John gave the police a statement, we knew him since we were in pajamas and now he wants to sell us out like that. He is a fucking goof, and he better get the fuck out of dodge before he catches the bullet train.

Goat's Hoof
The Manjur is a musical instrument used in the Arab states of the Persian Gulf but with East African origins. It is made of Goofs attached to a cloth. It is performed by tying the instrument around the waist. The performer shakes his or her hip to create a rattle sound when the goofs collide with each other. FACT.
