MURRAY, UTAH: 'Sister Wives' Season 18 star Kody Brown has invented a new word "plural monogamy."

According to Kody "Plural monogamy is where you're not functioning as one family, you're multiple families, a husband with 2 families."

According to Kody if a man is involved in polygamy and their sister wives' families do not interact with each other then that's called "plural monogamy."

Kody slams Janelle Brown for being a "monogamist" and being concerned about wanting Kody to spend time only with him.

The star believes the reason for the fall of polygamy was that each of the sister wives wanted him to spend time with them and not with others.

Janelle claims, "Kody is the one who actually brought up the word and the term plural monogamy and he acts like it was my idea."
