Some have characterized the "six, seven" meme as an example of internet "brain rot" -- a term for low-quality, meaningless online memes and the negative impact this content may have on consumers, which was named the word of the year by Oxford University Press in 2024.

"South Park" parodied the "six, seven" trend in a new episode earlier this month. A teaser trailer depicted faculty at South Park Elementary growing frustrated with students who "appear to be in some kind of cult involving the numbers six and seven." In the episode, teachers were so concerned about the "Satanic numerology" that they enlisted an "expert on the end of days and the coming Antichrist" investigate, who was revealed to be a parody of billionaire Peter Thiel.

Many teachers have documented the "six, seven" craze on TikTok, with some appearing visibly frustrated, while others use it as a tool to capture their students' attention. Some teachers have posted videos declaring they have banned the number "67" from their classrooms. Another teacher, in a video liked more than 2.5 million times, told his precalculus class: "You're idiots," before mocking the way students say "six, seven." One teacher posted a video of herself using "six, seven" as a call-and-response tactic to silence her classroom. She said the word "six," to which the entire class responded "seven," and then told students they have to be quiet after that and that is the "only way I'm going to let you say this ridiculous phrase." Multiple teachers uploaded videos pranking their class with the two numbers, giving students math tests where every answer is "67."

Skrilla's song "Doot Doot" went viral on TikTok earlier this year, with many users posting video edits of 24-year-old NBA player LaMelo Ball, who stands six foot seven inches, to the song. Ball acknowledged the trend in an interview with ESPN, stating he often hears kids yelling "six, seven" at him and joked the phrase is his new nickname. The trend was also boosted by a viral moment from a video of a basketball game, uploaded to YouTube by social media celebrity Cam Wilder, in which a boy exclaims "six, seven" into the camera while moving his palms up and down. The boy went viral on TikTok and was featured in many "six, seven" video edits. Other instances of people saying "six, seven" have gone viral on TikTok, like a crowd of people cheering as an In-N-Out employee calls out order number 67 and dancers giggling as their teacher says "six, seven" while counting out the beat. Gen Z and millennial TikTok users have also made posts joking about the "six, seven" craze making them feel old and out-of-touch with trends popular among kids.
