I did wonder about the name but I thought it was just some crazy new term I'd not heard of XD

Don't worry too much. Most native English speakers are used to figuring out what each other really meant. I think it's largely to do with technology and technical terms; so many have entered "everyday language" that it's confusing even to us. Swivel chairs do have wheels, after all; it would be a perfectly good term for them, if it didn't already mean something else.

And that's not to mention how annoyingly standard-free English is in the first place. (If you ever see a regular English verb, hunt it for a trophy, they're very rare!) A writer of my acquaintance once had a character of his, (a space alien), ask whether English was a language or a cypher code! It all comes from England having been conquered by so many other countries with other lenguages; Saxony, Breton, Normandy, Rome, the Vikings... By the time England went out and conquered it's own empire, the language was already structured so as to allow foreign words to be adopted easily. (It saved us the trouble of making up words for the various foods and things and places we "discovered," although the natives sometimes resented it.)

So really, don't worry about it.

LOL i wondered about it too but nevermind XD
