Question pertaining to DIBS?

Article 62 of the Bro Code reads:

" In the event that two Bros lock on to the same target, the Bro who calls dibs first has dibs. If they both call dibs at the same time, the Bro who counts aloud to ten the fastest has dibs. If both arrive at the number ten at the same time, the Bro who brought the last round of drinks has dibs. If they haven't purchased drinks yet, the taller of the two Bros has dibs. If they're the same height, the Bro with the longer dry spell has dibs. Should the dry spells be of equal length, a game of discreet Broshambo* shall determine dibs, provided the chick is still there."

The code has proceedings based on calling dibs first and at the same time. The question is whether or not there is any code that determines what happens if the Bros do not know who was first calling it.
