A few times recently, I’ve seen people round here saying that there’s a difference between a Beamer and a Bimmer, with one being a motorbike and the other a car. I’m pretty certain that’s a new idea, and the Beezer explanation is just folk etymology created to explain a difference people didn’t understand. It seems much more plausible to me that the two are the same word said in two different English accents: bimmer is northern, beamer is southern.
Does anyone have a verifiable example of anyone talking/writing about it before about 2010? What about back when BSA were still in business? What’s the earliest reference anyone can find?
Update: so far the earliest is 2005.
