This of course is the origin of the Forest term "butty" for a friend or team-mate.
The butty-man was the team leader (and not always a popular man since he controlled the wages of the team), but the men in the team were butties and so would call each other "butty".

I remember an uncle of mine who was an engineer at the Northern United colliery would often call me "me ol' butty".
