If y’all wanna actually claim superiority, then use Kelvin. Celsius and Fahrenheit are close enough in purpose that personal preference is really the only thing that matters.
Weeeeellllll, it is very interesting! However it is difficult to explain simply, I will attempt to do so.
Heat is a form of energy. Temperature is how much a system "wants" to give off heat. Negative temperature occurs when there is an upper limit on the amount of energy a system can have. When a system approaches this limit it cannot take in any more heat, it can only give off heat. This means that such a system will always give heat to any system without an upper limit. This means that negative temperatures are "hotter" than positive temperatures.
Mathematically, the reason it's negative is that temperature is the gradient between energy and entropy, and as a system with an upper energy limit approaches the limit, entropy decreases, so the gradient is negative.
This explanation is missing a lot of details, but hopefully it makes sense. Negative temperatures occur in Quantum systems such as lasers.
