Bone is one of those words that started out meaning one thing and has ?evolved? into many more. Its usual meaning is anything from 206-+ parts of a skeleton, connected to hold up your bodily form, or hard substance like ivory.
Tickling the bones could mean playing keys on a piano or slapping sticks together, rolling – throwing dice in a game, boning a fish, or the basics of a building, work of art, or writing. Then there’s the more risqué versions which I’ll not write here.
When I was a child we used to dance to a song named “Ain’t no sin to take off your skin and dance around in your bones” while my dad played the banjo. I couldn’t find a short version on YouTube. Have a great weekend, and dance around in your bones☺️
