* Someone who is excessively vain or self-absorbed: This is probably the most common usage. It refers to someone who tries to draw attention to themselves and their perceived attractiveness or accomplishments.
* Someone who is flamboyant or showy: This meaning is similar to the first, but it emphasizes the outward display of personality rather than just vanity.
* A person who is overly proud and boastful: This meaning focuses on a person's arrogant behavior and tendency to brag.
Example Sentences:
* "He's such a peacock, always trying to get everyone's attention."
* "Don't be such a peacock, it's not all about you."
* "He was peacocking around in his new suit, trying to impress everyone."
It's important to note that "peacock" can be a negative term, implying someone is being arrogant or conceited. However, it can also be used ironically or humorously to describe someone who is simply confident or charismatic.
