补刀
bǔ dāo
It is another popular gaming terminology! It is used to describe an attack on a dying person once more to make sure that he or she will definitely die.
This is similar to the English phrase: to “rub salt in the wound”.
This Internet slang term is later used to describe further mocking or rebuttal in communication.
An example would be:
"你的补刀技巧真强！“
ni de bu dao ji qiao zhen qiang
which translates to: "your rebuttal technique is really strong!"
