"Pov" probably stands for "point of view", which is common in storytelling, especially in films or books where the narrative is from a character's perspective. The phrase "kamu lagi mbak" is in Indonesian. Translating that, "kamu" means "you", "lagi" is "currently" or "now", and "mbak" is a term of respect/salutation for an older or higher-ranking woman, similar to "Ms." So putting it together, it might be something like "you are currently Ms. MiyaLuv51 Indo18 installing lifestyle and entertainment."
