rapa tu madre
Considered the most dangerous insult in the Dominican Republic, as saying it often leads to immediate and extreme violence like stabbings or shootings. (It is a vulgar way to insult someone's mother).
They might as well buy the coffin for Beni already: he told me rapa tu madre, just wait until I see him, I am going to kill that cocksucker.
