Noooo, everyone doesn't refer to everything differently. If they did, people would not be able to communicate. A banana is a banana, and if you call it a glogstick, no one will know what you're talking about. If people want to communicate clearly and effectively, where other people will understand them, they will use the appropriate language and vocabulary. Every industry has its own jargon and technical terms.
It's like the one guy who came up with, all on his own, a new name for the Highway Patrol in Louisiana - "In Louisiana we call 'em gators".
Well, no they don't. Not in Louisiana, not anywhere. The trucking industry knows gators to be one thing - parts of tires on the road - and he clearly didn't even know that much about the industry. If you want to call them "gators", and you're not talking about tire bits, no one is gonna know what the heck you're talking about.
Very recently someone here mentioned having to do fingerprint loads, and I and others naturally assumed they were talking about fingerprint loads, because the term fingerprint loads means something very specific in the industry. Anyone who uses the term to mean something else, especially something for which there is already an existing industry-specific term, is ignorant of the industry. Sorry.
