Birmingham

The word for shoddy goods is a local pronunciation of Birmingham.

Brummagem is a dialect form of the city's name, once linked to counterfeit coin and cheap plated ware. Brummie, for a resident, comes from the same form.

The city's own pronunciation of its name became an English word for cheap fakes.

Brummajem is a spelling of Brummagem, the old local form of Birmingham, produced by swapping the first two consonants and wearing down the rest. Because seventeenth and eighteenth century Birmingham turned out counterfeit coin and cheap plated goods, brummagem became an adjective meaning showy and worthless. The same contraction gives the city its modern nicknames Brum and Brummie.
