Idaho may be best known for its potatoes, but there’s far more to the Gem State than spuds alone. From the rugged peaks of the Sawtooths to the blue turf of Boise State, Idaho blends natural wonders with a distinctive small-town charm and pioneer spirit. Whether you’re cruising the highways of the Panhandle or cheering on the Broncos in the “City of Trees,” these 18 slang terms will help you talk like a true Idahoan.
The Gem State
Idaho’s official nickname, thanks to the abundance of gems and minerals found in its mountains and rivers. It’s a reminder that there’s more hidden treasure here than just potatoes.
Famous Potatoes
Idaho’s longstanding license plate slogan, proudly linking the state to its world-renowned spuds. Don’t be surprised if locals boast about the superior texture and flavor of Idaho taters.
Spud
A casual, affectionate term for the potatoes Idaho is famous for. In some communities, you might even hear “spud farmer” used as a badge of honor.
Boise (Boy-see, Not Boy-zee)
The capital city’s name is pronounced “Boy-see,” and locals take note if you say it wrong. It’s also known for its thriving arts scene, craft breweries, and a rapidly growing tech sector.
City of Trees
Another nickname for Boise, thanks to its tree-lined streets and greenery. If someone says they live in the “City of Trees,” they’re talking about Idaho’s booming urban hub.
Blue Turf
Boise State University’s iconic bright blue football field—perhaps the most famous in college sports. “We’re heading to the Blue” means catching a Broncos home game, with a stadium that stands out in more ways than one.
Bronco Nation
The collective name for fans of Boise State sports, especially football. On game days, you’ll see swaths of orange and blue all around the state.
The Panhandle
Refers to the narrow strip in the northern part of Idaho, from around Lewiston up to the Canadian border. It’s a land of lakes, mountains, and thick forests—just don’t forget your rain gear.
Sawtooths
A rugged mountain range in central Idaho, beloved for hiking, backpacking, and jaw-dropping views. If a local says they’re off to the Sawtooths, they’re in for some serious outdoor adventure.
Coeur d’Alene (Core-duh-LANE)
A resort city in the Panhandle, famous for its stunning lake and bustling summer tourism. Locals shorthand it as “CDA,” and they’ll correct your pronunciation if you mangle it.
The 208
Idaho’s primary area code (along with the newer 986). Saying “I rep the 208” is like declaring that you’re true Idaho, through and through.
Fry Sauce
A mixture of ketchup and mayonnaise (plus a secret dash of something else in some recipes) that’s a staple dip in many Idaho restaurants. It’s not just a Utah thing—Idahoans love it, too.
Finger Steaks
Breaded and deep-fried strips of steak that are an Idaho classic. Dip them in fry sauce, and you’ll experience a lesser-known—but beloved—piece of local cuisine.
Nap-Ida
A tongue-in-cheek mash-up of Nampa and Caldwell, two neighboring cities in Canyon County. Locals joke about them being so close, they’ve practically merged into one.
Tater Tot
While not exclusively Idahoan, these bite-sized potato gems feel right at home here. Anyone who grew up in Idaho probably has memories of tater tots at school lunches or backyard barbecues.
Potato Drop
Boise’s quirky New Year’s Eve tradition—a giant spud descends at midnight, similar to Times Square’s ball drop. Nothing says Idaho more than ringing in the new year with a massive potato.
U of I (Vandals)
Refers to the University of Idaho in Moscow, whose teams are known as the Vandals. Mentioning “Go Vandals!” might spark friendly (or not-so-friendly) rivalry talk with Bronco Nation.
Going Up to McCall
A phrase meaning heading north from the Treasure Valley into the mountains for a weekend getaway. Whether it’s skiing at Brundage Mountain in winter or enjoying Payette Lake in summer, McCall is a favorite spot for Boise folks.
These terms capture the essence of Idaho’s vast landscapes, outdoor adventures, and potato pride. By embracing this local lingo—pronouncing Boise like a pro, cheering beneath the Blue Turf, or savoring fry sauce with finger steaks—you’ll find yourself welcomed into the Gem State’s down-to-earth culture. So pack your hiking boots, pick out a Bronco or Vandal shirt, and get ready to experience the unbeatable charm of Idaho.
