Name given to Irish Immigrants in 19th century Glasgow(mainly Catholic),because when they went to get their daily meal from the soup kitchens,Scotch Broth was usually the served meal.Being generally of low genetic stock and having bigger bottom lips than normal humans,the broth tended to dribble down their chins,hence the name Brothmouth.
