A Ham Bone is an old phrase used for people who have a very high sense of themself. They will brag about how great they are at parties. Their stories get very old after various re-tellings. Most people have a relative who is a ham bone. They usually lack sincerity, but like to portray they do. Keep them away from your wives or significant others...
I recently saw Bruce Springsteen's One Man Broadway Show. What a Ham Bone.
