我毒舌我有病我瞎眼会爱你
[wŏ dú shé wŏ yŏu bìng wŏ xiā yăn huì ài nĭ]
This nickname is a paradoxical and somewhat self-deprecating expression. It translates to 'I have a sharp tongue, I'm messed up, I can't see clearly, but I will love you.' The speaker describes their own flaws or problematic behavior but expresses the idea that they still hold genuine affection despite this. This may also imply a kind of uncontrolled or fated emotion.
