So in 2016, Stanley tools wanted to release a new insulated 40 oz steel drinking cup, and they needed marketing copy. Their bright idea was to call it a "tumbler", a word which had previously meant a delicate cocktail glass. For whatever reason, their marketing copy completely rewrote American English, to the point that apparently large swathes of the American public no longer know what the word means!

And therefore, my wife and I nearly had nervous breakdowns this weekend over a very confusing argument about whether the kids should be allowed to take highball glasses to school this term!
