Confused with new names

[Nail Love]

Hi, Im hearing these "new to me" titles/treatment names etc, can anyone explain? Hollywood nails, the american, the holland.... what do they mean?

Hollywood usually refers to toenails, it's a French gel overlay.

American... that could be refering to an American manicure style?!?

No idea re the Holland one.
