Used in certain "Right Leaning" political groups online. Deceptively not an acronym, the meaning literally is to go faster because one wishes to accelerate to the inevitable "Collapse".

Then to call anything F/A/S/T means it has any of these concept implicit in it. I.e. a picture of a knight/samurai but holding a machine gun. Or really anything with an archeofuturist aesthetic.
