你一枪崩了我你一刀捅死我
[nĭ yī qiāng bēng le wŏ nĭ yī dāo tŏng sĭ wŏ]
It's a dramatic way of expressing extreme displeasure or frustration with someone, as if they have done something so terrible that one is asking to be killed. 'Either shoot me with a gun or stab me with a knife' expresses an intense emotional reaction of hopelessness or anger.
