Well, not medical, exactly. I used to work in a vet clinic, so I know quite a bit about animals, and people make some funny mistakes when talking about their pets. For example, the verb "to spay" is used for the removal of reproductive structures from a female animal. An animal who has had her reproductive structures removed has been "spayed." However, a lot of people would come in and say, "We had her (or him, sometimes) spaded about a month ago, and now she's getting fat."
One time I was at PetsMart and the person ahead of me in line was asking the cashier about Pit Bulls. The cashier pulled out a book about them, and there was a picture of one with a docked tail. I remarked that I had never seen one with a docked tail before, and the cashier retorted, "Some of them aren't born with tails. Believe me, I had two AKC-registered Pit Bulls, and they had naturally docked tails." First, the AKC does not register Pit Bulls. Second, Pit Bulls are all born with tails. Third, only fighting dogs have their tails surgically docked. So the woman was basically admitting to buying fighting dogs off of someone.
You know the spot on treatments that you squeeze onto your dog's shoulders to keep the fleas and ticks away for a month or more? Well, you aren't supposed to touch the liquid yourself because it's concentrated pesticide and it's not indicated for human use. So this woman brought her dog into the clinic and she wanted to get a pack of treatments and put one on her dog right away. We started to show her how to put it on and specifically told her never to touch it herself. She stopped us, saying, "I know what I'm doing. I've do this all the time." Then she squirted it directly onto her hands, rubbed them together, and patted it onto the dog's coat.
