radio waves sent and received by people's minds
Slang term, often used in contexts like conspiracy theories or science fiction to describe telepathic or mind-control signals.
彼は毒電波を受信したと言って、変なことを言い始めた。
He started saying strange things, claiming he had received mind-control radio waves.
Compound of 毒 (doku, 'poison') and 電波 (denpa, 'radio waves'), literally 'poison radio waves'. The exact origin is uncertain, but it likely emerged in subcultures to describe harmful or manipulative telepathic signals.
