nervio (this one’s Spanish): “a feeling of such intense affection that one trembles or grits his teeth with restraint so as not to harm the object of his affection.” (I guess it’s equivalent to the “I could eat you up!” feeling.)
(I got “nervio” from here, which is worth visiting because it has a picture of Picasso demonstrating the concept.)
The things you can learn from the interwebs!
So THAT’S where they got Austral-ia from!
