A state of being where you can have up to 7 spouses. Used a lot in Arabian countries. 3 bits (2 cubed) can store up to a value of 8, and you have 0 for no spouse, leaving you with 7 wives/husbands.
Yassin the Turk felt the limitations of the 3-bit marriage were too tight and converted to Cycle-Accurate Mormonism so he could have a 15-bit marriage
and have a bigger family.
