我让你万劫不复死而无墓
[wŏ ràng nĭ wàn jié bù fù sĭ ér wú mù]
Literally translating to 'I will doom you forever and let you die without a grave', this username represents someone who promises retribution or severe consequences to another party, perhaps in retaliation or anger. It has quite a harsh and intense tone.
