Porteño Idiom: Amigovio, -a
English Equivalent: Semi-serious boyfriend/girlfriend
English speakers are often frustrated by the fact that Spanish doesn’t seem to have a good translation for boyfriend/girlfriend. You can use novio/novia, but this has a pretty strong connotation and describes a relationship that is very serious.
Fortunately, Porteno, the Spanish dialect spoken in Buenos Aires, has come up with a fine alternative: More than an amigo, not quite a novio…Amigovio!
