What's your idea of shtf?

Hi, I'm new to this section, only just found it.
I've had a read of a few threads and a few people go on about skills/equipment etc for when shtf.
What is your idea of that?

Several per country that should probably be?

I wonder which one comes first? We've got a big cyber attack today where I live; I just heard about it, it's on the news.
