The song "Cockroach" by Joseph Arthur is a metaphorical exploration of a toxic and selfish individual. The lyrics suggest that this person is metaphorically poisoning those around them, causing harm and destruction. The repeated lines "You're putting poison here" highlight their negative influence on others. The lyrics also describe this person as a cockroach, emphasizing their ability to survive and adapt despite their destructive behavior. They are compared to a crawling insect, symbolizing their creeping presence and lack of empathy. The line "Crawling on bones" suggests that they thrive on the decay and destruction they create. The song suggests that this person is constantly engaged in manipulative behavior, only giving something to others if they can benefit in return. The lyrics imply that they will go as far as causing harm to those who cross them, expressing the sentiment, "If you get burned, you're gonna burn." The chorus of the song reflects the protagonist's detachment from this toxic individual. They express a sense of freedom and liberation, indicating that they have already moved on from the person's influence. The line "When you finally go away, I'm already gone" signifies their emotional detachment. Furthermore, the lyrics touch upon the consequences of the toxic individual's actions. The protagonist suggests that the negative energy they generate will eventually catch up with them. The metaphor of a demon leaning against their front door represents the impending consequences they will face. The lack of remorse or admission of guilt is criticized with the line "And still you could never admit that maybe you could have prevented destruction." Overall, the song "Cockroach" portrays the havoc caused by toxic individuals and highlights the singer's resilience and ability to move on from such negative influences.
