When a girl or guy breakup the other gets invovled into another relationship right away. Usualy within 2 weeks after the break up. The other person they are invoved with is known as the "backup". Look out for someone they have never introduce you too but yet they always have contact with. They will just say it is only a friend. But the "backup" is the person they go too if your relationship falls through
