1. She is my new buddy.

2. He is my new buddy.
=============
Is Sentence 1 above correct?
Can we us the word 'buddy' only for a man not a woman?


//"A buddy is a close friend, usually a male friend of a man."=> This is the definition of a dictionary.//

Both 1 and 2 can be used. Yes, a buddy is usually male, but not exclusively.

Sentence 1 is grammatically correct. The word "buddy" is generally considered gender-neutral, so it can be used for both men and women. However, it is true that the term "buddy" is often associated more commonly with referring to a male friend. It is also worth noting that the usage and connotations of words can vary depending on cultural and regional contexts.
