In Brazil before you are boyfriend and girlfriend, you can be “ficantes”. The concept is similar to a hookup
When you meet someone in a bar, night-club, bookstore, etc., and you hook up with that person, in Portuguese we use the verb “ficar”.
So a ficante is a person that you are hooking up with, without anything serious. A person that you are just “ficando”.
- O menino que você estava ontem, é algo sério?
- Nada, só ficante mesmo.
