81 Survival Acronyms and Terms Every Prepper Should Know

This post has been updated from our original Survival Acronyms and Terms post that was first published in 2017. We keep our content updated as the world around us changes, as we learn new skills and techniques, and (of course) when we learn new survival terms and acronyms.

Using shorthand to talk about specialized topics in communities is nothing new. Plenty of people are of the opinion that prepper acronyms just muddy up communication and cause a headache for newcomers. They argue that it drives people away from prepping and puts preppers in a bad light. Others insist that it establishes a sense of community, and improves communication flow with abbreviations.

Whether you are an avid survival acronym user or prefer to use plain English, knowing what they mean can come in handy when dealing with preppers. Below you’ll find our comprehensive list of prepping and survival acronyms and terms, split up by type and organized alphabetically.

ETA: Estimated Time of Arrival

FIFO: First in, First Out – a method of inventory management, used often in food storage, to cycle all inventory. Think of this method as working like a garden hose.

SIP: Shelter in Place – an emergency agency-directed order to seal off rooms and stay put to avoid volatile CBRN agent contamination.

SNAFU: Situation Normal- All F’d Up – another military crossover acronym not to be confused with SHTF or FUBAR. SNAFU simply means you acknowledge that everything is normal, and that is normally messed up.

SOL: Shit out of Luck

SOP: Standard Operating Procedure – a military-rooted acronym used often when developing plans, or relaying plans to others.

SOS: Save Our Ship – a recognizable signal for help, it is extremely recognizable when communicated with Morse code.

YOYO: You’re On Your Own – a prepper acronym name for how employees, soldiers, and police will inevitably abandon their station or mission to fend for themselves and their families in a bad enough scenario.

Prepping Terms

Besides abbreviating almost everything, there are a few words that preppers like to use. They include:

100 mph tape: A beefy duct tape popularized by the military with superior adhesive and weather-resistance.

550 cord: A specific rating of paracord (Type III) popularized by the military, with a tensile strength of 550 pounds.

Bug Out: Originating from British slang, ‘bugging out’ is a form of military retreat. In prepper and survivalist terms, it means to leave your area with survival kits to relocate to a (preferably a pre-designated) safe area. Mobile kits, such as ‘bug out bags‘ are needed to make this happen.

Bugging In: Opposite of bugging out, but ‘hunkering down’ with your own resources in the same area.

Bushcraft: Outdoor survival skills with a focus on making resources. Extremely popular in the UK, Australia, and Europe and growing in popularity elsewhere.

Carrington: the most intense geomagnetic storm recorded in history, back in 1859.

Faraday: a bag, case, or cage made out of sealed conductive materials to protect sensitive electronics inside from EMPs and CMEs.

Ham: often assumed that it is an acronym, but it is actually just slang for amateur radio operators.

Homestead: isolated homes that are usually self-sufficient, off-grid, and/or, agricultural work. Homesteading is everything that goes into setting up and running a homestead, and homesteaders are the people that do it. The Homestead Act of 1862 used to grant land for this use, but now free land is harder to come by.

Molon Labe: A Greek phrase μολὼν λαβέ meaning ‘come and take them’, often used in defiance of those that would challenge the US second amendment.

Off Grid: Living without supported services like electricity, phone lines, water/sewage lines, etc. “Going off grid” is usually a lifestyle choice that can be equated to homesteading.

Pollyanna: A blindly optimistic person in the face of real threats and danger- the hero of Eleanor Portor’s 1913 novel of the same name.

Prep: A specific resource, plan, or kit related to prepping, or just shorthand for the word ‘prepare’.

Prepper: Someone who is prepared for emergencies, disasters, and more (What is Prepping and What is a Prepper?)

Rule of Three: a survival rule of thumb describing how humans can only live 3 minutes without air, 3 hours without shelter, 3 days without water, and 3 weeks without food. We have a whole article breaking it down: The Survival Rule of 3 | Air, Shelter, Water, & Food.

Supervolcano: a volcano with a VEI over 8 and the capacity to cause a multi-regional natural disaster.

Survivalist: Often used interchangeably with ‘prepper’, but many survivalists will argue that they are more skill-focused instead of stocking resources.

Two is One, One is None: A common mantra in prepping that prepares for resource failure. We go over the origin and meaning in our article: Two is One and One is None | The Power of Redundancy.
