It's "zavináč" in Czech -- pickled herring. If you buy them in a jar, they're rolled up, looking a lot like that symbol.
My favorite name for “@“ is “rogue”
I prefer ”tourist”
What languages or cultures or regions use this form?
It's particularly popular in Yendor, I believe.
Spread from there to Ancardia and Moria as well, though.

In the 90s/00s it was often referred to as 'miukumauku' in Finnish, roughly translates as 'meowmeow', as in the sound a cat makes, since it somewhat looks like a sleeping cat.
In Russian, it's usually called `dog`. No idea why.
A dog will always perform a certain spiral inwards walk pattern before it comes to rest on bedding.
I forget the exact details, but I've seen it called a snail in some programming language or other - I remember getting an error message along the lines of 'unexpected snail at line x'! I wish I could recall what language it was - perhaps something verilog related?
In italian we call it "chiocciola", which translates to snail.
