The latest teenage craze is causing headaches at In-N-Out

""It's rare to find a window of time when the dining room at any given In-N-Out is empty. The fast-paced fast food chain always seems to pack 'em in, and it's not uncommon to find lines of dining room customers spilling out into the parking lot, just waiting to order. Once inside, the red-and-white eating areas are a mass of happy humanity, with customers toting red trays in search of a booth. But lately, some of those chaotic dining rooms have gotten even noisier, thanks to a purposefully silly internet meme that's taking the teen world by storm.""

""Anyone with a child at home under the age of 18 is certainly aware of "6-7," the absurdist teenage phrase (said as "six seven") that has become the bane of high school teachers and confused parents everywhere. The two-number phrase, accompanied by an up-and-down hand juggling motion, is meant to be meaningless; that's part of the fun. But the galvanizing force of the phrase, just the latest version of every young generation's embrace of a groupthink joke, has forced some places to begin cracking down on any use of "6-7."""

""At In-N-Out, videos of excited crowds waiting for workers to call out order No. 67 have begun to sweep the internet. In the videos, clusters of rowdy, harmless teams wait, phones ready to record, for the numbered callout on the dining room microphone like ravers anticipating a beat drop. Some employees seem to be in on the fun, excitedly playing into the living meme. Others, not so much.""

""The In-N-Out Reddit page is littered with mixed reactions to "6-7," from customers purposefully hiding their 67 order number to avoid causing a stir to, in one instance, a reported employee who states that their manager avoids having workers call out the number at all. Instead, they ring up order No. 67 as something innocuous, like a request for a water cup, and toss the slip into the trash.""

In-N-Out dining rooms often fill with crowds, and a new teen meme, "6-7" (said "six seven"), has increased noise and commotion in some locations. The phrase is absurdist and meaningless, accompanied by an up-and-down hand juggling motion, which appeals to teenagers. Videos show groups waiting and recording for workers to call order No. 67, with some employees participating and others resistant. Online community reactions vary, and some staff or managers reportedly avoid announcing number 67, disguising it as innocuous items like a water cup. The meme has led some venues to alter callout procedures to prevent disruptions.
