Best Friend
a person who one distinguishes as someone they are very close to, one they can trust, and one with whom they have fun. It can be considered that a person may have up to three best friends, or may also include a group of three best friends. Therefore, "best" does not just mean only one, and is used as a superlative to express hierarchy. Furthermore, allowing for the song from the comedic film, "The Hangover", to be played and have intrinsic meaning.
