Stands for Snowflake Automatic Defense System. Used by Snowflakes who react violently when one deems the comment to be offensive, regardless if it was or otherwise. Mostly occurs in members of Gunpla Facebook groups who post nub-ridden snapbuilds and poorly painted builds. Recently, people who flex the Gunpla they own (or do not own) and would often drop golden bracelets, satellites and bidets, if not mounds of cash they do not really have..
Hey, I see you posted a snap-built Gunpla, you might want to clean those nubs.

WTF? My money. My kit. My rulez. Nub-ridden snap-built Gunplas are the style trend now. Where is your Gunpla? Do you even build?

Oh my. Looks like your S.A.D.S. activated.
