Joe, from what I have found out looking for the song, bhoys is a term used for the team members of the Glasgow Celtics, whose arch rival is the Glasgow Rangers, both "football", ie, soccer teams. Bhoys and Ghirls is also used to denote fans of the Celtics. From what Nynia says, this is probably the biggest rivalry in sports. Huns is a derogatory name for the the Rangers.........I know that Soccer games can get really ugly, fan wise.
