bonnet
Or BONNETER, a gambling cheat. Sometimes called a "bearer-up." The BONNET plays as though he were a member of the general public, and by his good luck, or by the force of his example, induces others to venture their stakes. Bonneting is often done in much better society than that to be found in the ordinary gaming rooms. A man who persuades another to buy an article on which he receives commission or per-centage is said to BONNET or bear-up for the seller.
