πrate

πrate: noun. The (lamentably fast) rate at which pirates disappear from the world. The π in the word πrate, we were informed, comes from the radius of the world - the equator - around which the majority of pirates is found. According to our sources (the Church of the Flying Spaghetti Monster), the πrate is an indispensable component in the equation for calculating the rate of global warming, as scientists have found a very strong negative correlation coefficient between pirate numbers and rise in global temperatures.
