informer; loudmouth; blabbermouth
The origin of the word comes from "beater" (batidora) backwards, or "dor-ti-ba" that for reasons not clear led to "Ortiva" (no"D"and "V"). That is to say, they "whip up" gossip.
This is usually used in terms of crime, such the "ortive" being the blabbermouth who rats to the police.
Example: "No nos cagues, no seas ortiva" (We fuck with us, do not be an ortiva).
