bulger

In golf, a wooden club (especially a driver) characterized by a face that is convex and thus "bulges" slightly outward. It is no longer in common use. My grandpa's collection of old clubs even has a bulger in it. Sonny, this ancient artifact here is called a "bulger." Have you ever seen one before? A: "What seems to be the trouble, caddy?" B: "That guy just asked me to get his 'bulger,' and I have no idea what that is."
