Fast food is usually pretty boring. You’ve got a burger, some fries, and a soda. It's a formula. But back in the late 90s, Taco Bell realized they couldn't just keep being "the other guys." They needed a rallying cry. That’s where think outside of the bun comes in. It wasn't just a catchy jingle; it was a direct shot at the golden arches and the king of burgers. It told people that bread was a cage.
Honestly, the phrase became more than marketing. It defined a whole era of "fourth meal" late-night runs and questionable interior design choices involving purple and teal.
The Strategy Behind the Slogan
Brands don't just wake up and decide to change their identity on a whim. In 1997, Taco Bell was struggling with a bit of an identity crisis. Their previous efforts—think of the "Run for the Border" campaign—felt a bit dated. They hired TBWA/Chiat/Day, the same powerhouse agency that handled Apple, to shake things up. The goal was simple: positioning.
If McDonald’s and Burger King owned the "bun," Taco Bell would own everything else.
It worked because it was confrontational but playful. By telling consumers to think outside of the bun, they weren't just selling tacos; they were selling a rebellion against the sandwich status quo. It’s the kind of psychological positioning that makes a teenager feel like eating a Chalupa is a personality trait.
You weren't just hungry. You were an "outsider."
Why it Stuck for Over a Decade
Most slogans die in two years. This one lasted fourteen. Why? Because it was versatile. It allowed the brand to launch weird stuff like the Crunchwrap Supreme without explaining why it existed. The "bun" represented the boring, predictable American diet. Taco Bell represented the crunch, the spice, and the fold.

The Gidget Era and the Pivot
We can't talk about this slogan without talking about the Chihuahua. Gidget, the actual dog used in the commercials, became the face of the brand. While the dog usually said "¡Yo quiero Taco Bell!", the underlying message was always aligned with that think outside of the bun philosophy.
However, there was a problem.
The dog was too popular. People loved the Chihuahua, but they weren't necessarily buying more tacos because of it. It’s a classic business trap. Your mascot becomes a celebrity, but your sales remain flat. By the early 2000s, Taco Bell started leaning harder into the "outsider" messaging and phased out the pup to focus more on the food innovation itself.
They started experimenting with textures. Think about the Grilled Stuft Burrito. It wasn't a burger. It wasn't even a traditional taco. It was a brick of calories designed to be eaten with one hand while driving a 2002 Honda Civic. That is the physical manifestation of thinking outside the bun.
When the Bun Fights Back
In the mid-2000s, the fast-food landscape shifted. People started worrying about what was actually in the beef. Taco Bell faced a massive lawsuit in 2011 (which was eventually dropped) regarding the percentage of actual meat in their seasoned beef.
This was a turning point.

When your whole brand is built on being "different" and "outside the norm," any hit to your credibility feels twice as hard. If you aren't the safe, boring burger, you have to be the high-quality alternative. The company realized that think outside of the bun had run its course. It was a defensive slogan—it defined Taco Bell by what it wasn't (a burger joint) rather than what it was.
The Shift to Live Mas
In 2012, they killed the slogan. They replaced it with "Live Mas."
It was a move from a product-centric message to a lifestyle-centric one. Brian Niccol, who was the CMO at the time before eventually becoming CEO (and later moving to Chipotle and Starbucks), was a huge driver of this. He understood that the modern consumer didn't need to be told to avoid buns—they already knew they wanted something "tasty and twisted."
"Live Mas" was about the experience. It opened the door for the Cantina locations that serve alcohol and the Taco Bell Hotel. You can't really do a "Think Outside of the Bun Hotel" without it sounding like a bread-free commune.
The Lasting Impact on Modern Advertising
You see the fingerprints of this campaign everywhere today. When Liquid Death sells water like it's a heavy metal concert, or when dbrand mocks its own customers on social media, they are using the DNA of think outside of the bun.
It’s about "enemy positioning."

To win in a crowded market, you don't just say you're good. You pick a fight with the category leader. You make the standard option look like the "old" way of doing things.

What Businesses Can Learn From the Bun
If you're running a business or a brand, you don't necessarily need a taco. But you do need a bun. You need that thing that everyone else in your industry is doing so you can point at it and say, "Not that."
- Identify the Default: What is the boring, standard version of your product? For a law firm, it might be the "stuffy suit." For a software company, it might be the "complicated dashboard."
- Create the Contrast: You can't just be better; you have to be different. Taco Bell didn't say their beef was higher quality than McDonald's (which would have been a hard sell anyway). They just said it wasn't a burger.
- Commit to the Bit: Taco Bell didn't just use the slogan in ads; they changed their menu to reflect it. They invented shapes of food that didn't exist in nature.
- Know When to Leave: If your brand evolves, your slogan has to, too. Taco Bell grew from a budget taco stand to a lifestyle brand. "Live Mas" fits the $7 luxury burrito world; the old slogan fits the 59-cent taco world.
The reality is that think outside of the bun was a perfect moment in time. It captured the 90s spirit of "extreme" everything. It gave us permission to eat a taco at midnight and feel like we were making a bold life choice.
Even though the slogan is officially retired, its soul lives on every time Taco Bell releases something like a taco shell made entirely of fried chicken. That is peak "outside the bun" energy.
Next time you're looking at a project that feels stale, don't ask how to make it better. Ask what the "bun" of your industry is, and then move as far away from it as possible. That’s where the real money—and the real fun—usually stays hidden.
Actionable Insights for Brand Positioning
- Audit your competitors' visuals: If everyone is using blue and white, your "outside the bun" move is to use orange and purple. Look at how Taco Bell's neon interiors stood out against the "wood and brick" look of older Wendy’s locations.
- Find your "Enemy": Not a specific company, but a specific habit. Taco Bell's enemy was the boredom of the sandwich. Identify the habit your customers are stuck in and offer the escape hatch.
- Keep the language simple: "Think outside of the bun" is five words. All of them are one syllable. It's easy to remember, easy to say, and easy to parody. If your value proposition takes a paragraph to explain, you're still stuck inside the bun.
- Test the "So What?" factor: If you tell someone your product is "innovative," they don't care. If you tell them it's an alternative to the thing they're tired of, you have their attention. Focus on the relief you provide from the mundane.
