Ohhhh, hyperbolic functions. I knew this would get silly.
Eveyone with a sense of a math, like brain (like me, I got c+'s almost EVERY year!!), would know that hyper means fast-like, so you meant hydrobolic, cuz, I know that dillo's and water and cold don't mix, they melt like the wicked old witch in the Wizard of Oz, that is why they live down south!
my three cents!
