What do you mean, kill me without a puppy knife?

For the questioner's question, "don't kill me with a dog knife" is a common online expression, which means that I hope others will use a gentle and euphemistic way when criticizing or satirizing themselves, rather than using words that are too direct or hurtful. It is equivalent to saying "please be gentle" or "please don't hurt me".

This online expression comes from an online novel "Choosing Heaven", which contains a dialogue: "Kill me with a big dog knife, not a puppy knife". Later, this sentence was spoofed by netizens and widely circulated, becoming a humorous expression.
