bi-level
noun. a haircut that is short in the front and long in the back - see mullet.
We saw many bi-levels at the State Fair.
Bi-Level Mode
Wearing a long-sleeve shirt, sweater, or jacket with shorts in order to maintain upper and lower body thermal comfort. Named after the air conditioner mode in a car where cool air comes from the face outlets and warm air from the foot outlets to maintain superior comfort. This also allows for the easy transition to Max Cold mode (short sleeves with shorts) at a moment's notice.
It's sunny but cool today, so I'm going to rock Bi-Level Mode.
