ha ha ok I was just looking it up and they name Borgs by numbers.... like what ever number you get assimilated in your group...
ex: your name could be
DOUG 5 of 6
that means you were the 5th guy out of 6 to be assimilated
you might even say something like Northwest A.K.A. 6 of 8 (just made up numbers I really dont know how many mergers there have been)
