(NewsNation) — In-N-Out Burger is saying “bye bye, 6-7” after the viral trend wreaked havoc at many of its stores, People magazine reports.

The burger chain confirmed that “67” no longer appears on customer orders, disappointing the many teens who had been lining up to hear the number called. An employee at a Los Angeles location told People the change was made about a month ago, adding the company has also banned the number “69.”

Speculation about the removal first surfaced on Reddit, where one user noted: “Everytime I would get to number 66, and then get to the next customer, it would just go to number 68, and it would skip 67.”

Others quickly chimed in, linking the decision to the “6-7” trend.

Sometimes written as “67” but pronounced “six seven,” the slang term is frequently said while alternating between lifting your hands, palms up, in a sort of juggling or weighing motion.

The term, which went viral online, was named Dictionary.com’s word of the year, despite ongoing debate over whether it qualifies as a word at all.

Dictionary.com said its annual selection is a linguistic time capsule reflecting social trends and events. But the site admitted it, too, is a bit confused by “6-7.”
