#BuffaloKids - "Trẻ trâu" in Vietnamese, basically teenagers with an inflated ego. Often recognized by their distinct dress style (like the case with Russian gopniks), and their rides on bikes without wearing helmets and sometimes in illegal positions. They may form gangs and fight each other using improvised sharp weapons. Look it up.
