British term meaning to be married to their weapon.
Brown Bess. The Army Musket 1700-1815

In the days of lace-ruffles, perukes, and brocade
Brown Bess was a partner whom none could despise -
An out-spoken, flinty-lipped, brazen-faced jade,
With a habit of looking men straight in the eyes -
At Blenheim and Ramillies, fops would confess
They were pierced to the heart by the charms of Brown Bess.
Rudyard Kipling 1865-1936
