Act 1 scene 1 introduces the theme of masculine honour. What does this mean and how is it displayed by the characters?

Masculine honour is a testosterone fuelled show of strength and invincibility against another male. The Montague boys and the Capulet boys exchange a few insults in the market. They both try to get the last insult in which leads to a brawl. Each side wants to prove their masculinity through a show of strength and violence.
