best friend by default

When one has only one friend and must rank them as their best friend due to the fact that there are no runners up.

Person 1: Hey man who is your best friend?
Person 2: Bob; he's my best friend by default.

Best friend...by default

When someone tells you you're their best friend but you are painfully aware you're their ONLY friend.

Chum: "you're my best friend"
Lee: "yeah! Best friend...by default!!"
