In-N-Out Burger has reportedly had to remove a specific number from its ordering system amid a viral trend.
People have started to notice that the number is missing, with some customers taking to Reddit to find out what's been going on.
One wrote: "While I was at work yesterday night, I noticed that every time I would get to number 66, and then get to the next customer it would just go to number 68, an it would skip 67. Now I'm curious on if or why they removed it."
Now, if you're aware of the whole '67' craze, then you might have an inkling about why the chain has made the decision.

Pronounced as 'six-seven' rather than 'sixty-seven', the term has been popularised by Gen Alpha, and seems to originate from a song by rapper Skrilla, titled 'Doot Doot (6 7)'.
However, it increased in popularity when it was used on clips of NBA players including LaMelo Ball, who is 6 feet 7 inches in height.
If you've got kids in your family, you'll likely have heard them enthusiastically screaming 'six-seven' - with a particular emphasis on 'seven' - should the number be mentioned at all.

Which, according to PEOPLE, is one reason why In-N-Out Burger has made the decision to remove the controversial number from the ordering system.
According to the outlet, one employee has confirmed that the number was removed around a month ago, and banned from the ticket system.
Over on Reddit, another person said: “Viral 6-7 all the kids are yelling these days. My in n out also skips this after a while kids kept making a commotion when the number was called."
Another added: "I was number 67 like two weeks ago. and the way all of my fellow patrons cheered when I was called up was one of the coolest moments of my life."

And a third joked: "They removed it after receiving the 67th written compliant about screaming kids."

The term has since been chosen as Dictionary.com's word of the year, described as 'a viral, ambiguous slang term that has waffled its way through Gen Alpha social media and school hallways'.
The dictionary explains: "While the term is largely nonsensical, some argue it means 'so-so,' or 'maybe this, maybe that,' especially when paired with a hand gesture where both palms face up and move alternately up and down.

"Because of its murky and shifting usage, it’s an example of brainrot slang and is intended to be nonsensical and playfully absurd."
