Maverick Trevillian is an 
American child who became an Internet celebrity, widely known as the "67 Kid" or "6-7 meme kid". He gained fame in March 2025 after a video of him enthusiastically yelling "six seven" with an accompanying hand gesture at a basketball game went viral on TikTok and Instagram Reels. The "6-7" phrase originated from a rap song and became a popular meme in basketball culture, referencing the height of some players. Trevillian's unique and exaggerated delivery of the meme helped propel it to widespread recognition across social media. 
Following his initial viral fame, his image was incorporated into a variety of other internet trends, including photo edits in an "analog horror" style known as "SCP-067 Kid". He has an official Instagram account, managed by his parents, where he posts content related to the meme and promotes ads. As of late 2025, he is believed to be around 12 years old, in the 7th grade
