The first thing to happen will be a warrant for your arrest. If you or your family member/friend is caught and brought back to jail, it is very unlikely that they will be able to post bail again.
When you jump bail, you essential forfeit your bail, meaning you lose that 10% you put down and have to pay the full amount. If a family member or friend paid the amount of the bail, they are now responsible for paying it in full.
Depending on what type of crime you were originally booked for, they will add on charges and jail/prison time.
