Unfortunately, I cannot generate the meaning or story behind a specific song as it is subjective to the interpretation of the listener. The lyrics of "Black Enforcers" by Guttermouth appear to be abstract and open-ended, leaving room for personal interpretation. However, based on the given lyrics, it seems like the song may be referencing a group or organization called the "Black Enforcers." The lyrics emphasize their actions and enforcement during the night, possibly symbolizing a clandestine or secretive nature. The mention of a handshake and the repetition of "9 times against the wall" suggest some form of initiation or test required to be part of the group. The lyrics also mention the enforcement being done with "artillery force" and the mention of Jay Santos, possibly implying their authority and power. Overall, the song appears to revolve around the theme of a mysterious group with strict entry requirements and a reputation for enforcing their orders or rules. Again, it's important to remember that this is an interpretation and the true meaning of the song can vary depending on the perspective of the listener.
