It is a prevalent hand gesture in the Indian subcontinent. Could mean a lot of things, and interpreted along with the facial expression. In this case, it means "That's pretty cool", looking at her facial expressions.

It could mean "What the heck is going on?", when accompanied with a different facial expression.

Exactly the same in Italy. Weird, that.

Surprisingly, as an Italian, I know exactly what this means: “wonderful, amazing, perfect”.

as an Italian, I understand this as "to steal"

I’d denote stealing with my palm facing downwards.

I actually had to try it out in real life... I can’t think of gesticulating in the abstract.

Seems like you can take the Italian out of Italy but not Italy out of the Italian.

It means "wow, impressive".

looks like that clip of her is looped, so it might just be a random hand movement that looks meaningful bc you see it twice

wow, i sure feel dumb about this now! thank you, sibling commenters who actually know stuff :)
