Why do some of my voice memos get random default names?

I guess I don’t mind anyway and instead find it quite funny but I’m writing this anyway. Sometimes, my voice memos are named (seemingly?) random things instead of my location 😂 - I’ve had ‘Virginia bliss’ which got me questioning everything x10 when I looked it up and also ‘Tropical Blender’ (?) which defo isn’t somewhere I’ve been if it is a place! Well, it always gives me a bit of interest in my life so I’m okay with it :) thanks Apple, my phone’s fine xx
