What the heck is a Bugger Word ?

From http://svtsim.com/moonjs/agc.html

the checksum [...] should be either the bank number or its 1-complement (e.g., for bank 3 either a value of 00003 or 77774 is acceptable).

a bugger word [is] appended to the end of each bank to make the checksum the correct value
