One of the worst acronyms in the history of mathematics, stands for hyperbolic sine. Only dickish math teachers teach things like this to their students just to confuse them. If your math teacher starts teaching you this and other hyperbolic stuff, expect the worst.
Math Teacher: "Ok now I'm going to teach you hyperbolic functions. Let's start by talking about sinh."
Student: "Someone get me a gun."
Student: "Someone get me a gun."
