The "Trojan Horse" meme originates from the ancient Greek myth of the Trojan War. According to the Aeneid, Greek warriors constructed a massive wooden horse as a gift, secretly hiding inside it. The Trojans, believing it to be a peace offering, brought it into their city, leading to their ultimate defeat when the soldiers emerged at night. The meme signifies a deceptive tactic where a seemingly harmless or beneficial entity is introduced, but it secretly contains a hidden threat or agenda that leads to negative consequences. It's widely used to comment on situations involving hidden dangers, backroom dealings, or accepting something at face value without understanding its true, often malicious, intent. It highlights irony, naivety, or strategic infiltration.
