What does the coldness of a cold joke mean?

The definition of a cold joke is actually a failed joke, which means that a joke itself can't achieve the funny purpose because of boring, homophonic words, translation, subject omission, logic, different judgments or special content, or because of the performer's tone or expression. But it doesn't mean that the joke itself is boring, which is also a manifestation of humor. Nowadays, most people laugh when they hear cold jokes, and sometimes they make a gesture of hugging their arms: "It's so cold!" " Or words and expressions related to cold semantics, such as chills, temperature, air conditioning or hot weather.
