Thermostat Battle 

The intense, although very sneaky, altercation where two or more inhabitants of the same living space continually adjust the thermostat to their respective preferred temperatures, without the knowledge of the other person(s).

I set my thermostat to 65 degrees last night, and now it's at 80! My roommate must be declaring a thermostat battle!
