Thru Hiker Slang/Jargon

The world of long distance hiking/thru hiking is an intriguing one. It’s a tight knit and dare I say… quirky community that takes care of its own. Aside from taking care of its own, you might even call it a subculture, or a counterculture of conventional society – full of even more sub/countercultures within it. As with any culture, they usually come with their own customs, traditions, sayings, dialects, or ways of communicating or getting information across. If you were a fly on the wall listening to a few thru hikers banter back and forth about various trail related things, you may find yourself with more questions than answers. Many jobs, hobbies, cults, clubs, religions, factions, creeds, ideologies, political affiliations, and certain circles of friends have their own unique methods of communicating through various slang/jargon that makes it easier for those familiar with the group (harder for those unfamiliar) to understand them; the thru hiking community is no different. Here I’ve compiled a list of some of the most common and not so common hiking/thru-hiking terms/jargon you might hear or use while out on the trails. I don’t have absolutely everything listed here, but I’ve got most of it. As you might suspect, many people end up creating their own terms for certain things and wind up using them exclusively among their close trail friends/family. Enjoy!

-Trail magic: Kind deeds from thoughtful strangers in the form of food, rides, favors, or anything that impacts your hike positively.
-Thru-hike(r): The official spelling and term that describes completing the entire length of a long trail in a single attempt. To be considered a single attempt, the hike must be completed the same year it was started. Some believe in order to be a thru-hike, you cannot leave the trail for an extended period of time, regardless of whether you complete the entire thing in a year or not. 
-Thorough Hike:
This is a term that refers to completing a “thru- hike” in a slightly slower than average time, due to intentionally taking your time to “smell the roses” and enjoy yourself.

This has two meanings. It can refer to cutting straight through the forest in an attempt to bypass switchbacks or bends in the trail. It can also refer to hiking while simultaneously smoking marijuana, or hiking while “high.”

Stump bear:
A large tree stump, or uprooted tree that you momentarily mistake for a bear when you first see it. This is usually accompanied by a slight heart attack, depending on who you are and how close the stump bear is when you notice it.

Also, referred to as a “Zero Day,” hikers say “Zero” for short. It refers to a day in which you hike zero miles. Zero basically means you took the day off for whatever reason.
Pronounced “Near-O,” this is a shortened term for “Nero Day,” or a day in which you hike almost zero miles. Depending on who you are, a Nero Day will usually constitute hiking less than five or ten miles.
Vitamin “i”:
This is what “Ibuprofen” is referred to out on the trail. This is the go to medicine for most people when they are “hurting” or in pain.

Hiker Medicine:
This is a broad term that can refer to anything that makes you feel better, dulls any pain, or improves your hiking (in your own opinion) in one form or another. Ibuprofen, Marijuana, alcohol, and most other substances are sometimes referred to as Hiker/Hiking Medicine.

  1. Don’t overlook the humble “Section Hiker”, who, due to work, family or perhaps health or age concerns, takes on only a one or two-week section of the trail. Some section hikers have cumulatively and over many years covered nearly all the trail. section hikers tend to be looked down upon by Thru-Hikers, but make up the great bulk of ATC members and hikers.

  2. I think that AYCE ( all you can eat) deserves a mention, as these establishments are great morale boosters, and develop a rep among always-hungry hikers.

  3. Great info! What about saddle? I often stop for snack breaks when I’ve reached the saddle.
    I love your pictures and stories!!! Can’t wait to hear more!

  4. Heya Mayor, the term “Hiker Trash” can be assigned to any hiker, not just thru-hikers. I consider myself hiker trash and I am a section hiker and wear the badge with pride. It’s a moniker based on a hiker’s deteriorating living and hygiene conditions, behaviors, dress, etc…not whether or not one has completed a thru or not. I’ve gotten nasty enough plenty of times to have earned the badge, haha.

    1. That is true! I hunted most of these down from other pages on the internet and modified some of them while adding others I knew but couldn’t find anywhere online. I should have elaborated more on that one

  5. I knew some of these but certainly not all of them. Great photo of you and Katana! It looks like you are in a gear junkies heaven:)

  6. Heh heh heh. You said knob. Heh heh. Heh heh heh. We have a trail up here in southern Indiana called the Knobstone, sorta like The Roller Coaster on the AT.
