Dormostat
The part of the leg that sticks out from under the covers to regulate your body temperature while you sleep.
"I just couldn't sleep. When I have the cover on, I feel hot. When I have the cover off, I feel cold. I had to use my dormostat to go with it."
"Cold. Hot. Cold. Hot. Cold. Dormostat Out. Uh comfy."
"Cold. Hot. Cold. Hot. Cold. Dormostat Out. Uh comfy."
