Turk: Cool trick.
Dr. Casey: You should try it. It's great for dexterity, concentration, and convincing single women you're a power dork.
The coin walk, also known as the coin roll, knuckle roll, or steeplechase flourish, is a dexterity trick where a character rolls a small object across their fingers, usually over the first joints. This can be done in either direction, and the thumb and pinky finger are used to "catch" the object and shift it back to the index finger to start the roll over again. It's usually done with something round and flat like a coin or poker chip, although other objects can be used.
This trick requires a good bit of flexibility and skill to do smoothly, and sometimes a character will be seen practicing it or demonstrating it to another character. Others may do it just because it conveys an immediate air of coolness or badassery. It may also demonstrate or imply being in a profession where such nimbleness is helpful, or can simply be a Character Tic.
