"Tawuran" is a term typically used in Indonesia to refer to street fights or brawls, often involving students or youth groups. While the exact tradition of "tawuran" may not exist in the US, there can definitely be instances of street fights or gang-related violence. However, it's important to keep in mind that these kinds of violence are not exclusive or unique to any particular country and are generally illegal and considered harmful to society. Always prioritize safety and avoid getting involved in these types of situations.
