我不是白痴而是黑痴
[wŏ bù shì bái chī ér shì hēi chī]
This nickname plays on words with the terms '白痴' (bai chi, meaning idiot) and '黑痴' (hei chi, implying being a fanatical follower or obsessed with something dark or gloomy). It humorously expresses someone's preference for darker obsessions over ignorance.
