What does it mean when your friend say he not your best best friend then he says it in your face?
Sounds like he's not your best friend.
Pretty self explanatory. He's not your best friend
The face of a best friend shows it all and one is able to judge you using your face. I think your friend learnt that you are not genuine in your friendship and that's why he decided to say that he is not your best friend.
Some one probably said they don't like you and he/she was embarrassed so he said that find a new best friend he's not worth it be a leader not a follower
theeeenn he's not ur best best friend.
Find someone else. Who isn't a dikface.
