A variation on the shotgun rule used when there is no clarity on who has earned the shotgun spot. Do-over can then be called and immediately after it is said shotgun can be recalled, whoever gaining in undoubtably earning the shotgun position. Who ever is calling the do-over obviously will have an advantage to call the shotgun immediately after; this is only fair. A do-over can not be called by a neutral party. Do-over's can be called in spite of any silencing game variations to a shotgun such as the jinx variation. A do-over cannot be called on a do-over, it is, as Aristotle might call it, the final cause.
Mike, Jermall and Max are walking towards Mike's ride.
Jermall: SHOTGUN NO...
Mike: Jermall Jer...
Max: PERSONAL JINX!
Jermall: DO-OVER BLITZ
At this point Jermall walks proudly to the shotgun seat.
Part of the shotty rule that allows do-over to be called when there is fighting over who earned the shotgun. Whoever, calls shotgun after the do-over gets shotgun no exceptions
Mark and Tony were fighting over who called Shotty first until Tony called Do-over and got the front seat no questions asked.
