你我非良人
[nĭ wŏ fēi liáng rén]
Translated into English as 'You and I are not good people', it might come across rather boldly or directly. However, in some specific cultural settings or story backgrounds, this phrase can be used humorously or ironically to describe situations where the person or character feels a little mischievous but is still amiable and harmless. Thus it doesn't exactly carry any negative connotations and may just reflect the user's quirky and self-mocking nature.
