Since the explanation on the pole is deceptive, why put it on the pole for the sake of macho man and keep it from the woman?

This sentence may refer to a scene of telling jokes. A man is making up some lies for him in order to make another man laugh and protect the lady from hearing inappropriate words. The man spoke with a pole and explained that the content was false, perhaps to show off humor and deepen the atmosphere, or to convince another man of what he said. In this process, the man may make up these lies out of the mentality of making himself look funny or out of the mentality of protecting others from being offended by others. This way of telling jokes and relaxing is very common in people's lives.
