SA is something awful forum apparently. We should define these terms!
One of the great things about the internet is you can search for the meaning of things you don't know. I know everyone on HN loves to use these[0][1], but not everything needs to be cited.
[0] meaningless footnotes
[1] you're not writing a term paper
Nobody asked for a citation, and good luck googling two-letter abbreviations unless you're lucky with guessing the right context words.
Thankfully somebody said forum. Googling "SA forum" will have correct top result.
Even duckduckgo knows that 'sa forums' is Something Awful. Also TFA writes out Something Awful several times throughout and doesn't exclusively use the abbreviation.
