SSTS is Message Board or Chat shorthand for "Snickering Softly To Self" in the same vein as LOL which is message board shorthand for "Laugh Out Loud"
Posting SSTS in a message or chat usually means you are too jaded to LOL and hold everyone else in sophisticated disdain.

SST
Scenario Specific Term: A term or acronym you use almost never because it describes something in such high detail. Most people acquire various SSTs but maybe get to use them once if they are lucky. Known to clutter minds of those who pay far too much attention to science or anything that overuses abbreviations.
John: My baby has an ELBW
Harry: Okay well what could that possibly mean.
John: Come on, its a term we learned in health class. It means Extremely Low Birth Weight.
Harry: When could anybody ever use that SST?
John: Oh you mean Scenario Specific Term? Well... right now?
Harry: I hope you enjoyed it. I don't think you'll ever use that one again.

Dae Quanne: I'm reading and astronomy magazine... what in god's name is an AO4ELT?
Jerry: That is what we call Adaptive Optics for Extremely Large Telescopes.
Dae Quanne: So basically just a major SST?
Jerry: What's an SST?
