This is a more dramatic word for "masunog." It's not just burned, it's *consumed*. Like when you forget the sinaing on the stove and it turns into a black brick. "Hala, muntik nang **matupok** ang bahay!" It’s also used figuratively for being consumed by strong emotions, like jealousy or anger. "Huwag kang magpadala sa galit at baka **matupok** ka nito."
