你一枪打在我心口说我爱你我笑着问你可以再打一枪吗
[nĭ yī qiāng dă zài wŏ xīn kŏu shuō wŏ ài nĭ wŏ xiào zhe wèn nĭ kĕ yĭ zài dă yī qiāng ma]
It means 'You shoot me in the heart saying you love me, I laugh and ask can you shoot one more time'. This could be used sarcastically to describe being heavily impacted or overwhelmed, likely due to a romantic confession but finding amusement rather than despair amidst intense feelings.
