Definitions if things

Where do I find the definitions of all the abbreviations... Example:POV and BDSM

I just did a google search of "ECCIE Hobby acronyms" There are many links to choose from which I found valuable as there are many different abbreviations as well as interpretations of each one..i.e. SS is one that seems ambiguous across many different posts. Good luck
