7 Shocking In-N-Out Burger Secrets And Viral Trends That Changed The Menu In 2025

Contents

The iconic red and yellow logo of In-N-Out Burger remains a beacon of West Coast fast-food culture, but the chain is anything but stagnant. As of late 2025, the company is making massive headlines, not just for its cult-favorite burgers but for controversial viral trends and an aggressive expansion strategy that is rewriting its geographical boundaries. This article dives into the freshest updates, the most photogenic secret menu items, and the shocking reason why the number '67' is now banned from the ordering system.

For decades, In-N-Out has maintained a simple, quality-focused ethos, resisting the urge to constantly change its core menu. However, the influence of social media and a significant push into new territories are forcing the company to adapt in unexpected ways, making 2025 a landmark year for the California-born institution.

The Viral '6-7' Trend and In-N-Out’s Banned Order Number

One of the most bizarre and unexpected pieces of news dominating the In-N-Out conversation in late 2025 was the removal of a specific order number from its entire system. This unprecedented move was a direct response to a viral social media trend that swept across platforms like TikTok and Instagram.

The Rise and Fall of Order Number 67

The number '67' became the center of a massive youth trend, often dubbed the '6-7' meme, which gained so much traction it was even called 2025's 'Word of the Year' by some online communities.

  • The Trend: The '6-7' meme involved customers ordering their food and then waiting specifically for the number 67 to appear on the screen, often performing a specific dance or chant when it was called.
  • The Disruption: This trend caused significant slowdowns in the drive-thru and dining areas, with groups congregating and causing minor chaos, disrupting the famously efficient In-N-Out operations.
  • The Solution: In an effort to restore order and speed, In-N-Out Burger made the drastic decision to remove the number '67' from its ticket order system entirely. Customers will now see the order numbers jump from 66 directly to 68, effectively shutting down the viral craze.

This event highlights the unique challenge modern fast-food chains face in managing their image and operations in the age of viral internet culture. It’s a fascinating, if frustrating, chapter in the company's 77-year history.

Massive 2025 Expansion: The Eastward Push into Tennessee and Beyond

While the company is known for its slow, deliberate growth primarily in the Western United States, 2025 marks a major acceleration in its expansion strategy. The biggest news is the long-awaited move into the Southeast, with the state of Tennessee being the first major target.

This expansion is a significant move for the privately-owned chain, overseen by owner and president Lynsi Snyder, as it requires establishing a new corporate hub and distribution center far from its California roots.

New In-N-Out Locations Opening in 2025

The company is on track to open seven new U.S. locations in 2025, signaling a rapid period of growth. The anticipation for these grand openings, often accompanied by long lines and celebratory photos, is immense.

Tennessee's Debut:

The first wave of Tennessee locations is expected to open by the end of 2025, bringing the iconic Double-Double and Animal Style Fries to the Southeast for the first time.

  • Lebanon
  • Antioch
  • Murfreesboro
  • Franklin

West Coast and Mountain State Growth:

In-N-Out is also bolstering its presence in existing and adjacent markets, with new stores slated for California, Arizona, Colorado, and Washington. Furthermore, the company has confirmed plans to expand into New Mexico for the first time in 2027, solidifying its commitment to broader geographical reach.

The Ultimate Visual Guide to Photogenic Secret Menu Items

The "Not-So-Secret Menu" is where In-N-Out truly shines for enthusiasts and photographers alike. These custom orders, which rely on the standard ingredients, are the most frequently photographed and shared items online, providing endless fresh "In-N-Out Burger images." Mastering these orders is essential for any true fan.

5 Must-Try Secret Menu Burgers and Fries

These entities are the core of the In-N-Out experience, offering unique textures and flavor combinations that look incredible in photos.

  1. The Animal Style Burger: This is the most famous secret item. The burger is prepared with mustard grilled into the patty, extra spread (a thousand island-style sauce), grilled onions, and pickles. The combination of textures and the signature messiness makes for a perfect, mouth-watering photo.
  2. The Flying Dutchman: A low-carb hero, this is simply two slices of melted cheese sandwiched between two burger patties. It’s a minimalist's dream and a surprisingly photogenic item due to its pure, unadorned form.
  3. The 4x4 (Quad Quad): For the truly hungry, this burger features four beef patties and four slices of cheese. The sheer height of this colossal burger makes it a stunning, clickbait-worthy image for social media. A smaller, but still impressive, version is the 3x3 (three patties, three slices of cheese).
  4. Animal Style Fries: A messy masterpiece. The standard fresh-cut fries are topped with melted cheese, the signature In-N-Out spread, and a generous layer of chopped grilled onions. The vibrant colors and rich toppings make this a highly shareable image.
  5. The Grilled Cheese: A simple yet satisfying option for vegetarians or those wanting a lighter bite. It features two slices of melted American cheese, lettuce, tomato, and spread on a toasted bun. You can also customize it with Grilled Onions for added flavor.

Lesser-Known Customizations for Topical Authority

To truly establish topical authority, understanding the deeper layers of customization is key. These items are less common but highly valued by hardcore fans:

  • Protein Style: The ultimate low-carb hack. Any burger can be ordered "Protein Style," meaning the bun is replaced entirely with large, crisp hand-leafed lettuce wraps. It offers a clean, fresh visual contrast to the traditional bun.
  • Onion Wrap: A newer, highly popular secret menu item. This is essentially the Flying Dutchman (patty and cheese) wrapped in grilled onions instead of a bun or lettuce. The deep caramel color of the grilled onions is incredibly appealing in close-up shots.
  • Roadkill Fries: A very unofficial, yet popular, combination where Animal Style Fries are topped with a crumbled Flying Dutchman burger patty. This is the definition of fast-food decadence.
  • Toasty Buns: A simple request that changes the texture of the burger. Asking for "Toasty Buns" ensures the buns are left on the grill a little longer for a crispier, more substantial bite.

The enduring popularity of In-N-Out, from its historic connection to the NHRA Pomona Dragstrip to its current viral trends, proves that a simple menu, when executed perfectly and paired with a strong brand identity, can create a global phenomenon. Whether you are capturing the perfect photo of a 4x4 or waiting for a grand opening in Tennessee, the In-N-Out experience remains one of the most celebrated in American fast food.
