Get the July 7mug. Six Seven originated from Skrilla’s song “doot doot” Where Skrilla says “6-7, I just bipped right on the highway (Bip,bip)” The meme was then popularized by the Rod Wave Elite player Taylen Kinney who said 6-7 and did a Jessie with his hands as shown in the gif. Taylen maximized the memes success by launching his water brand 67 Water.
