noun. A medical field that is so crucial when you injure your blah-blah bone.
Real citation: "There were a couple days there that I thought we were going to have to check my 5yo into a Kindergarten rehab for the psychotic! He was in so much pain that he was climbing the cabinets to get to his painkillers that I put in the cabnet over the sink. I am not telling you to scare you, just to let you know that this is (according to our doctor, who was the head of ortho-yada-yada-ology, ENT, at Texas Children's Hospital in Houston) very normal."

Made-up citation: "Some doctors leave the field of ortho-yada-yada-ology for a quiet life of meditation and poetry, but only the doctors who are cuckoo for crystal meth puffs."
