像是一个蛊
[xiàng shì yī gè gŭ]
Using traditional culture, 'a kind of witchcraft' can be an expression for bewitching or fascinating qualities. The nickname may describe oneself as mysteriously charming or complex and unpredictable, like the ancient poison mixture called '蛊' (literally means sorcery or infatuation) that has magical power in ancient Chinese mythology.
