Talking of temper ...
When I was quite young (pre-teen), the decorator would come around to "do the distemper" and I couldn't understand why we'd get someone in to spread disease. It wasn't as if we even had a dog.
Every time he came around, my gran would talk about the distemper and I'd be perplexed, but since asking even a simple question was 'cheek', frowned upon and likely to lead to physical punishment, I said nothing.
It was only rather later that I learned that distemper is both a traditional breathable interior paint as well as a canine viral infection. It's curious to use the same word for both, and I found it most confusing. We never had a dog in the house, but I don't think the paint was a repellent.
