BritishinformalA child’s expression used to make a claim to something:bags I his jacket...
Sweeney used to say, in Ireland, 'Bags I that.'
Bags I the hot dogs (inside) rather than the bottle stall (outside).
Here we say, 'bags I' instead. As in: bags I the chainsaw, bags I the best seat in the house, bags I the biggest piece of cake, and bags I the last beer....doesn't mean you always get it, tho.
