The song "Piranha" by Exodus is a heavy metal song that depicts a violent and destructive force of nature through the metaphor of piranhas. The lyrics suggest that piranhas represent a way of life, slicing jaws and wasting mankind. They are described as Loki's (a Norse god associated with mischief) pets, implying that they are cunning and deadly creatures. The song further emphasizes the danger posed by piranhas, portraying them as being trapped in swamps by the gates of hell. The listener is warned against ever letting them out because if they escape, a bloody battle will ensue. The chorus of the song reiterates the aggressiveness and mercilessness of piranhas. It suggests that if you try to challenge them, you will be swiftly overwhelmed. The repetitive phrases "Piranha kill in a pack - you'll run" and "Piranha start to attack - you're done" emphasize the inevitability of defeat against these creatures. The lyrics also mock the notion of being able to survive their attack, saying that if you think you can live, you're a fool. The verses continue to describe the destructive nature of piranhas. The gates of hell are depicted as old and cracked, allowing the piranhas to escape. As they are unleashed, they form a bloody wall of death, intent on killing anything in their path. Their sole mission is depicted as stripping bones and flesh, ripping out eyes, tearing off faces, and inflicting agonizing deaths. Overall, "Piranha" by Exodus is a song that uses piranhas as a metaphor for a relentless and deadly force that cannot be reasoned with or overcome. It serves as a warning against underestimating the destructive power of nature and the consequences of unbridled violence.
