Day one is a term stolen by basic women (and men) for their "insta" captions. It references a person that is close friend. The term is really referring to someone that has been there since your day one and therefore should only be used by twins who have a literal day one.
Thats my twin he is my actual day one.
A day one is someone who you know beyond time. Someone who is always in your life even when you're reincarnated they will find the way to find you back again. Ride with me and I will die for you. We always got eachother his/her back. Shorty here for the rescue
