Overview

• Explainer pieces published Sept. 29 trace the trend to Skrilla’s track “Doot Doot,” whose “six‑seven” refrain was clipped and looped across TikTok, YouTube Shorts, and Instagram.
• Edits featuring NBA guard LaMelo Ball, who stands 6-foot-7, helped popularize the audio before a viral courtside video of a child shouting “6-7” made it ubiquitous.
• The viral clip paired the phrase with an up‑and‑down hand motion that became the default in‑person emote for kids repeating the numbers.
• Creators and commenters describe the phrase as purposefully meaningless and fun to say, with one TikTok analyst noting it functions as playful filler rather than a set definition.
• Teachers report mixed responses, from bans to classroom tactics that co‑opt the chant, while online remixes have turned the “67 kid” into increasingly eerie, analog‑horror style edits; some coverage suggests the trend may be peaking as adults catch on.
