Day one

Your ride or die bestie, someone who is down to ride and by your side 24/7. Doesn't ask for anything but your loyalty, but would give you everything they have.

Justin is my day one!

A one from day one

Someone who’s been with you since the beginning and generally supports you. (Could be from the beginning of a certain period of time or situation.)

My Mom has been with me all my life. She is my A one from day one.

John is my A one from day one. We started this job at the same time.
