Stitching acronyms can be quite funny . You need to be familiar with them because they can come up on social media and if you are not sure what they mean you lose the meaning of the post sometimes because the extended writing isn't there to explain or contextualise the acronym. The Crocheter's code came up on DailyCrochet's Facebook page and it's a good start. SLIKstitches has a very comprehensive list. It's a quilting blog which is worth a visit if you are at all interested in quilting.
