Churrasquinho de gato – Cat barbecue

Any bbq of questionable origin (it isn't necessarily actually made of cat).

Pastel de ar - Air pastel

A pastel is a kind of popular pastry in Brazil that can be savoury or sweet and has varying flavours (I'll make a post on it in the near future, but for now, think "deep fried pita pocket"). 

An air pastel is a pastel that has very little filling inside (the bigger the pastel, the ore likely this is to be). The idea is that since there's so little filling, the filling for that pastry is "air".
