Not to be confused with 1337 (year). This article is the Robloxiapedia version of the 67 meme.
1337 (pronounced "thirteen three seven" also written as 1337, 13 37, 13-37 and 13-3-7) is an Internet meme and slang term that emerged in 2025 on BloxTok and BloxTube Shorts. It has no fixed meaning.
In March 2025, a boy named Bloxerick Trevillian became known as the "1337 Kid" after a viral video showed him yelling the term at a basketball game while performing an excited hand gesture. Multiple news outlets have linked the meme to the wider brainrot phenomenon, digital media deemed to be poor quality.
Origins
The slang originated from another slang "LEET". As 1 looks like L, 3 looks like E, and 7 looks like T. When used, 1337 usually means elite, which is the word that LEET comes from. 1337 can also refer to LEETspeak, which is when people replace letters with numbers that look alike.
1337's identity as a slang term has allowed it to spread in offline contexts, especially in schools, with some banning its use due to its disruption in the classroom. The numbers are used without any fixed meaning, instead functioning as an inside joke.
1337 Kid
On March 31, 2025, a Bloxtuber posted a video titled "My Overpowered AAU Team has Finally Returned!" (stylized in all caps) in which a boy, Bloxerick Trevillian, later nicknamed 1337 Kid, is seen going up to the camera and yelling "thirteen three seven" while performing a hand gesture in which he moves his hands up and down with upward-facing palms.
In August 2025, social media users begin creating photo edits distorting Trevillian in a bizarre or grotesque fashion likened to analog horror. This meme, called "RSCP-1337 Kid", satirizes the RSCP Foundation, a collaborative fiction project about fictional paranormal anomalies. "RSCP-1337 Kid" is not to be confused with the canon "RSCP-1337", which is about an anomalous hitchhiker.
