How did you know that my birthday's saturday? I did your horoscope, remember? I was gonna do everybody's, until sheldon went on one of his typical psychotic rants.
Como você sabia do meu aniversário? - Eu fiz o seu horóscopo, se lembra? Eu ia fazer o de todo mundo, até o Sheldon ter um de seus típicos surtos psicóticos.
A rant is an argument that is fueled by passion, not shaped by facts. When the shouting starts on talk radio, or when a blog commenter resorts to ALL CAPS — you're almost certainly encountering an instance of ranting.
rant - Ao pé da letra é discurso retórico. Reclamação, desabafo, arenga
