2. (Accies) A corner shop in Scotland.
3. A football (soccer) team from the west of Scotland. Full title: Hamilton Academical.
The usage of 1 & 2 is linked- due to the large numbers of Pakistani and Indian immigrants who owned shops. Usage is sparse nowadays- except in the West of Scotland, around Motherwell and Hamilton- where the obvious geographical link between the phrase and the place of usage is apparent. Definition 2 is also acceptable in Northern Ireland.
