ñampiro
A bottom-of-the-barrel criminal with a despicable reputation, likened to a demon. A ñampiro is characterized by extreme violence and a complete lack of scruples, engaging in theft, murder, and drug use, and even going as far as stabbing their own friends and family members. (In Colombia, this term describes someone considered far more dangerous and depraved than a common street thug).
He is worse than a hoodlum, a street dweller, a street urchin, a crackhead, and a gang member. In short, he is the most dangerous criminal in the world.
