What did she learn exactly?
It’s less about her I think – she has a whole team of people/companies/lawyers managing her music and it’s distribution globally.
I think it’s more of a question of why this wasn’t flagged prior to release by “her people”. Or maybe it was flagged, but ignored on the basis that (if you just look it up in Merriam-Webster, as above) it just presents as a fairly generic slang term for a clumsy person.
Where as (in this case), I obviously see how the term “Spaz” is offensive, and would never use it myself, I’m not 100% convinced that we need to examine the aetiology of every single slang term that we use to determine whether it might hypothetically cause offence (again: not talking about spaz – that’s just offensive). “Bulldozer” above is a great example. If the above is true, I understand that it has a pretty awful origin – but it simply doesn’t mean that any more: A bulldozer is something else, and people are using it (correctly) in that context.
I’m absolutely not part of the “it’s PC gawn maaaaad – you can’t say anything any more” brigade – but I think that people have to accept that language evolves in both directions. Ie: I think everyone accepts that there are things that were acceptable to say 10, 20, 30, 50 years ago, that you can’t/shouldn’t say any more. But I think we also need to accept the other side of that coin: that certain words/sayings have become so detached for their original root, that they just don’t mean that any more.
