You may tell a newly dating couple that its destiny for them to be together; thats its meant to be. When two people are meant to be best friends, instead of saying they're destiny, you would say that they are bestiny...They are bestinies. Person A: "Jamie and I are besties. We come from completely seperate worlds and backgrounds, but we're somehow best friends." Person B: "Oh you two are besties? No, yall are bestinies!"
