Person1: I saw your bestie yesterday he was asking about all through
Person2: the bond so close bro we get to miss each other all the time

Basically someone who knows your whole life story and is always there for you. Someone who puts up with your annoying sarcasm and listens to your long day rants and buys you food and has the prettiest smile and can always make you smile and is someone you are obsessed with.
