Six-seven may be a popular catch phrase, but some students and teachers at Rio Americano have heard it enough. 

A senior football player in one IM3 math class never missed a chance–and in math class, there are a lot of chances–to call out 67, adding the palms-up, up-and-down hand gesture like someone imitating a scale. Warnings went unheeded, he continued to call out 67, sometimes with a chorus of other students joining in. Finally, according to students in the class, the teacher assigned him to Wednesday school.

Both teacher and student are part of a national trend, with students posting thousands of videos of themselves saying 67 on TikTok and teachers posting videos about how frustrating that is.

Spiking in September and October, there are more than 2 million posts using the hashtag #67, according to TikTok’s analytics.

The math teacher declined to be interviewed for this story.

Students have mixed reactions to the trend. 

“While the 67 trend is definitely silly and meaningless, I still find it funny, especially when used in the right context,” senior Hailey Toth said. “A lot of my friends make jokes with it at home, school, and in sports. I think part of the humor is that it is just a harmless joke, but so many people understand or know it so it can be applied anywhere.”

Some students are just over it.

“Pretty much everyone has laughed at or done the 67 trend at some point,” junior Petra Al-Rayes said “I think it’s just another small trend that is popular at the moment, but that we will all cringe at in the future. Personally, I thought the trend was funny near the beginning of the school year when the trend was in full swing; however, as time went on, the trend became less funny and more immature.” 

Senior Mason Hamilton said, “ I think it’s a very dead meme that’s not going to pass, because people think it’s hilarious but it’s not anymore.”

The 67 trend began last spring, after rapper Skrilla released a song called “Doot Doot” in 2024. In the song he sings, “The way that switch brrt, I know he dyin’ 6-7.”

People who use the slang say it doesn’t mean anything; it’s just fun to say.

Skrilla told the Wall Street Journal the same thing: “I never put an actual meaning on it, and I still would not want to.” He said the absence of meaning is “why everybody keeps saying it.”

But those hunting for meaning say Skrilla was using 6-7 which could allude to a street in Philadelphia and a police code, 10-67, which is used to report a death. This verse acknowledges the chorus as it’s centered around a homicide case. 

“At first I hated the 67 joke a lot and thought it was really annoying and unfunny,” junior Avery Popejoy said. “But, after hearing the song it comes from play at hoco (homecoming), I started hecka vibing with it. Now I say it’s probably a little to much.”

As for the senior in the math class. He still does it along with other kids, say students, but not as often and not with the same response from the teacher. (She just tells him how “nonsensical” it is, a student said.) 

Perhaps he’s learned his lesson in Wednesday school, or perhaps the trend is fading.
