From Grok: Musical Roots: The Song That Sparked It The phrase traces directly back to the drill rap track "Doot Doot (6 7)" by Philadelphia rapper Skrilla (real name: unknown, but he's part of the Philly drill scene). Release Details: The song was unofficially dropped in December 2024 and officially released on February 7, 2025.
Key Lyrics: The hook features Skrilla rapping lines like "6-7, I just bipped right on the highway (Bip, bip)" over a trap beat. The "6-7" repetition is catchy but ambiguous—speculation includes: A nod to 67th Street in Skrilla's hometown (Philadelphia) or Chicago's Englewood neighborhood, tied to gang culture and drill rap themes.
Police radio code "10-67", which signals a report of death or a deceased person (e.g., "10-4" for acknowledgment, so "10-67" for something fatal). Linguist Taylor Jones has suggested this fits drill's gritty storytelling.
No confirmed "official" meaning—it's more vibe than literal.
The song itself has explicit lyrics about street life, violence, and bravado, which has led some parents to raise eyebrows about kids mimicking it without context.
