Abbreviation for when the shit hits the fan.
I survived a year of shtf in Bosnia in the 1990’s.
When your problems hit suddenly, pile up on top of you in an overwhelming manner with increasing severity, and you feel things might get increasingly worse if you don't deal with it ASAP.

Whether if you are living anywhere in the world, you know good and well that when disaster occurs, whether it is suddenly or looming over the horizon, just get ready in case SHTF... because it WILL.
