There are so many acronyms out there. 

The rise of text messaging and social media has made prompt communication something that is incredibly desirable, so acronyms and abbreviations are just all over the place. 

Because there are so many acronyms, it can be difficult to keep track of all of their different meanings. Sometimes, they can even be more confusing and time-consuming than helpful. For many people, SHTF is one of those acronyms. 

So, today’s word of the day is SHTF. We’re going to break down the meaning of SHTF, a little bit about the phrase’s history, and how to use it in a sentence. 

Let’s get started. 

What Is the Definition of SHTF?

SHTF is an acronym for a fairly common phrase in the English language. It stands for “shit hits the fan” or “stuff hits the fan” if you’re looking for a cleaner version. Here’s the definition of that phrase:

  • The moment when impending negative events finally happen

How Is SHTF Used?

The phrase is primarily used in American English. It’s used in a lot of different situations to talk about the moment when things start getting bad or when disaster strikes, and it implies that the consequences of this event will be messy, unavoidable, and chaotic.  Obviously, because of the profanity, it’s mostly used in casual conversation.

The phrase “shit hits the fan” itself may be quite common, but the acronym carries a slightly different meaning behind it. SHTF mostly has connotations with prepper culture. Preppers are people who are expecting an apocalyptic event and are preparing for it by gathering the equipment and resources necessary to survive that event, such as food, weapons, shelter, and more. 

So if you’re online and you see somebody using the acronym SHTF, that person might be a survivalist referring to an impending natural disaster, nuclear war, pandemic, or another catastrophic event. They likely have the know-how to survive a significant doomsday event or SHTF event. 

What Is the History Behind SHTF?

The phrase “shit hits the fan” has been around for quite some time. It popped up in American English in the early twentieth century. 

Electric fans were invented in the 1880s, so it took a little while for phrases to be made surrounding the new invention, but by the 1930s, it finally happened. Thus, the phrase “shit hit the fan” emerged. 

It isn’t completely clear how the phrase came into existence. One popular theory is that it came from an old joke that actually came out of Canada. The joke goes like this: 

There was a man in a crowded bar who needed to relieve his bowels, but he couldn’t find the bathroom. So he went upstairs from the party, found a hole in the floor, and used that. Once he returned downstairs, everybody had left except for the bartender who was hiding behind the bar. The man asked him what happened, and the bartender responded, “Where were you when shit hit the fan?”

The theory goes that the joke became quite popular and spread throughout English-speaking countries. But there isn’t any way to verify this theory. 

Doomsday and SHTF

In the 1990s, the phrase evolved again. People who feared the end of the world or survival situation took to new online forums to discuss theories of how the world will end, strategies for staying alive and self-defense, and what to do in case the power grid failed, and there was a mass power outage. 

As these forums boomed in popularity, they developed their own lingo and slang, and the acronym SHTF began to refer specifically to the moment that the disaster happened. They refer to these as SHTF scenarios or SHTF situations. 

As they are prepping for the end of the world as we know it, they share their experiences on these forums and will commonly use the acronym SHTF in their discussions.
