Bestie 2: "what's a bestie anniversary??"
Bestie 1: "it's like a dating anniversary but for best friends!! A bestie anniversary!!"
Bestie 2: "that's so cool!!"

Get the bestie anniversarymug. A swiftie bestie refers to a best friend who is one of the most amazing people ever. It is a person who is very kind and very trustful. It is a person who is very talented but does not accept it because they are very humble at the same time. Overall this person is best best friend that one can ever ask for.
My best friend from Wisconsin is very talented and very kind. She is very trustful and can be trusted with anything. Overall she is an amazing swiftie bestie.
