A person who knows you better than any one else. When you insult them they just laugh and come up with something even more offensive then what you said. A bestie has 500 pictures of you, you hope no one will ever see. They know what makes you happy and what makes you sad, they can tell right away if something is wrong. they can say you are weird, stupid, idiotic, etc. and you can just laugh.
