Answer:
He means that He is crying or weeping because of the death of his family
Explanation:
The playbook titled Macbeth was written by William Shakespeare. When Macduff says that he is behaving like a woman in Act 4 Scene 3 of Macbeth, he means that "He is crying or weeping because of the death of his family."
The scene captured Ross from Scotland giving Macduff the sad news that his wife and children have been killed by King Macbeth.
While Macduff was trying to cope with the sad news, Malcolm told him to remain strong and channel the anger towards revenge.
In response, Macduff declared that "Oh, I could play the woman with mine eye, And braggart with my tongue! But, gentle heavens, Cut short all intermission..."
This implies that he could go on crying like a woman...
