你一刀捅死我说是手哆嗦你一枪打死我说是枪走火
[nĭ yī dāo tŏng sĭ wŏ shuō shì shŏu duō suō nĭ yī qiāng dă sĭ wŏ shuō shì qiāng zŏu huŏ]
In a sarcastic and dark humor tone, it roughly translates to: 'If you stab me and claim it’s a slip of your hands; if you shoot me dead and say it's because of the gun accidentally misfiring'. It refers to an absurd excuse given after doing harm.
