Funny about the Brazilian names! My hubby lived in brazil for a few years and says the same thing, there are crazy names! He met several people named after pop culture references, like a guy named Highlander (after the tv show) and another guy whose first name was Arnoldschwarzenegger. Lol!
There are some crazy names in my neck of the woods too. The (unofficial) rules lots of parents seem to follow... If it ends in an -ee sound it's a girl name, if it ends in an -en sound it's a boy, and whatever crazy combination of letters you want to put in front of it- the weirder the spelling the better. For example I've heard Taylee, Nayvie, Payzlee, Kynlee for girls and Braigen, Zayden, Treyton for boys. It's a weird Utah/Idaho/Arizona thing I think and I'm not sure why. But I made sure all my kids had names you've heard before and don't follow these "rules" lol! No offense to anyone who likes names like these of course, just not my cup of tea!
