Piracy is a capitalist propaganda term for the act of illegally sharing copyrighted information such as non-free books, movies, music, video games or scientific papers.
It is greatly admirable to support piracy, however also keep in mind the following: if you pirate a proprietary piece of information, you get it gratis but it stays proprietary, it abuses you, it limits your freedom -- you won't get the source code, you won't be able to publicly host it, you won't be allowed to create and share derivative works etc. Therefore prefer free (as in freedom) alternatives to piracy, i.e. pieces of information that are not only gratis but also freedom supporting.
