Step 1 : Introduction to the question "1. What is the right polite meaning of the acronym SSDD?"
...1. Share sortie, divide defilade 2. Super-secret death dealer 3. Super-scary death drop 4. Same stuff, different day A phrase stating an observation that nothing has changed and the anticipation that the situation will remain as-is. Sources on the internet attribute this acronym to Stephen King's book "Dreamcatcher" - I believe they are incorrect. It has been in use since before the publication date of the book (2001) and I believe it to be an old U.S. Army acronym.
