Before I read that far into your post, I assumed it was a nn for Lachlan! So, there's inadvertent gender-bending for a start. And I suppose the fact that it could rhyme with a childish diminutive version of words like sock and clock doesn't help. If I thought that way, which I don't, I'd have put an -a on the end of Covid and named her Vida.
Oh dear, I've just thought about the Locky Horror Picture Show. Good earworms for me; not a good life sentence for her.
