What is the definition of Thoracodynia02?

"Thoracodynia02" - a funny, albeit not entirely funny, term for a peculiar condition that involves an overactive thoracic spine, the part of the back between the neck and the ribs. Picture this: "The thoracodynia02 patient couldn't even take a deep breath, let alone laugh about it, because every time they inhaled, they'd accidentally trigger their own internal wind turbine."
