Decoding “6‑7”: The Hidden Meaning Behind Skrilla’s Drill Anthem

When Philadelphia rapper Skrilla dropped “Doot Doot (6‑7)” in late 2024, it immediately caught the attention of drill fans and meme culture alike. Most listeners recognized it as another hard-nosed Philly drill track — short, sharp, and street-cold. But beneath its clipped verses and hypnotic hook lies a riddle circulating on TikTok, in classrooms, and across social media: what does “6‑7” actually mean?

After breaking down the song, exploring its lyrical nuances, and understanding the global drill lineage, it’s clear — “6‑7” is a deliberate nod to the Brixton-based UK drill crew 67, whose reputation for brutality has shaped the genre internationally.

Breaking Down Skrilla’s “Doot Doot (6‑7)”

The song opens with pure bravado:

“Yeah, it’s Skrilla, yeah, it’s Skrilla.”

This repeated chant isn’t filler — it establishes identity, signals dominance, and primes listeners for the violent narrative that follows.

Then the chorus drops:

“Shooter stay strapped, I don’t need mine /
Bro put bolt right to they behind /
The way that switch brrt, I know he dyin’ /
6‑7, I just bipped right on the highway.”

Each line paints a scene with surgical precision: a firearm discharged (“switch brrt”), a target hit (“I know he dyin’”), and a swift exit (“bipped” = drove off quickly). And right in the middle, 6‑7 — landing like a calling card, signaling street-level knowledge and respect.

The verse continues:

“Shades on, I boul with the glasses /
Bro say er 'cause he a savage /
So many dead opps, so many ashes /
You ain't catch that, I can't pass this (Come here)”

Here, Skrilla layers street credibility, detachment, and keen observation. References to “shades” and being “savage” reinforce controlled aggression. “Dead opps, ashes” underscore the stakes, and the last line asserts vigilance — nothing escapes him.

Why “6‑7” Is a Nod to Brixton’s 67 Crew

Listeners have speculated wildly: Philadelphia streets, Chicago blocks, police codes, or viral TikTok memes. But the context leaves little doubt. 67 is the most infamous UK drill crew, emerging from Brixton Hill, South London.

• Formation: Early 2010s, shaping UK drill into a darker, slower, moodier style than Chicago drill.

• Notoriety: Known for real-life violent reputation; their music reflects gang rivalries and street activity.

• Influence: Tracks like “Let’s Lurk” with Giggs helped define UK drill aesthetics — tempo, cadence, and lyrical coldness — that global drill artists reference today.

Skrilla, steeped in drill culture, embeds “6‑7” right after describing death, signaling a deliberate homage to 67’s cold, unflinching legacy. It’s short, sharp, and chilling — street coldness distilled into two numbers.

Numerology and Symbolism of 67

Numerology adds an extra layer. The number 6 symbolizes balance, responsibility, and protection, while 7 represents introspection, mastery, and higher understanding. Together, 67 reflects the intersection of precise action and calculated intent — a fitting echo for a lyric depicting lethal skill executed with calm precision.

• “6‑7” in context: operates on multiple symbolic levels — death, coldness, and controlled power.

• Connection to “six feet under”: intensifies the metaphor of finality, reinforcing the theme of lethal efficiency.

This combination of street homage, numerology, and lyricism makes Skrilla’s “6‑7” a multi-layered cultural signifier, not just a numeric tag.

Drill’s Global Feedback Loop

Drill music is a transatlantic conversation: Chicago birthed it, Brixton weaponized it, and Philadelphia reclaims it. References flow freely between continents, creating codes, nods, and stylistic echoes that fans intuitively recognize.

By invoking “6‑7,” Skrilla situates himself in this lineage, acknowledging the ghost of 67 while maintaining Philly street identity. It’s a subtle but unmistakable mark of respect for drill history, violence, and artistry.

The Number as Myth

“6‑7” is succinct, brutal, and precise. It’s a salute to Brixton’s 67 crew, an emblem of street coldness, and an extension of death imagery — all encoded into a two-syllable lyric.

Cold world, no feelings, 6‑7 on the highway.

It’s a reminder that in drill, numbers aren’t arbitrary; they carry history, geography, and cultural storytelling.
