Volume Balancing
Usually taking place at night time when one's whole family is asleep, it is the art of watching something on TV, and turning the volume up and down so as not to disturb others, while keeping the volume enjoyable for yourself.
Ben: The explosion scene is coming up! Let me turn down the volume so I don't wake up my mom...
Max: Dude, nice volume balancing!
