Snowman

Snowman is an esoteric programming language created by Stack Exchange user Doorknob.

Hello World!
In Snowman, the Hello World program is very easy to understand. It looks like this: ("Hello World!"sP The program works by first making variables a and f active. Then, "Hello World!" is automatically put into a, the first undefined active variable. Then sP (or sp) prints the string out (sP = String Print).
