Best friend

A best friend, also known as a Bff, is someone who has your back and still cares about you after every fight. You should be able to tell them anything without worrying about their reaction. They will stay loyal to you and will love you for who you are. Even you you have lots of other friends, your best friend is still your favorite. A best friend doesn't ditch you for other people, even if you're mad. If you're so-called best friend lacks at least half of these traits, you should find someone better to spend your time with.

"You know that pretty girl over there?"
Me: "Yes! That's my best friend."
