Commonly used acronyms and nicknames

Being an exceptionally technology and magic-heavy modpack, GTNH comes with a large variety of items and materials with long names that earn themselves various acronyms and nicknames, especially on the Discord server.

This is intended to be a non-comprehensive list of known acronyms and nicknames for various things in the modpack.

Please help to add new acronyms as they come into common use.
