A word used by almost every Winnipeger , mostly by wannabe 6/10 models to describe guys they expose after they DM them. Also, used by guys that want to get laid with those models.
It's a acronym used in prisons. It means Good Only On Friday. Way back when on fridays in the joint, shipments/mail would come on a friday. The prisoner who was good for nothing else would be good only on friday, when they had new smokes, or gifts, or whatever. You'd then procceed to beat them up and take their shit.
