nickname a Protestant, especially a supporter of Glasgow Rangers football club. This goes back to William of Orange, and is now most familiar from the song (to the tune of 'Marching Through Georgia') which is used as a football battle-hymn: 'Hurrah! Hurrah! We are the Billy Boys; / Hurrah! Hurrah! We make a lot of noise; / We're up to here, we never fear – we all are Billy's sons, / We are the Glasgow Billy Boys. / We belong to Glasgow, we're Orange and we're true / Scotland is our country, our colours white and blue, / We're Protestants and proud of it , we're known near and far, / Glasgow Billy Boys they call us.'
