An instrument used to measure the temperature. This instrument is located between a man's legs and moves up when it is cold and down when it is hot. Although it will not tell the exact temperature, it can tell if it is cold as balls or hot as balls.
1. It's so freaking hot out here that my man thermometer is sticking to my leg.

2. I'm so cold my man thermometer is shriveled up and hurts.
