I don't know if it actually means anything, but I'm pretty sure it originated from a rap song
It comes from a rap song, and is randomly mentioned in the same verse we mentioned a guy dying.
10-67 is the police code for murder or homicide… and we all know that rap music is the terrible thing people in the hood listen too…
Even if it’s just coincidence, it stems from violence and death. Everyone says it’s “meaningless” but there are evil forces at play trying to corrupt the youth (even more than they already have been) with mindless memes and phrases.
