A conglomerate of the words monogamy and monotheist, which mean one partner and one God, respectively. A monogamytheist is someone who worships, glorifies, and generally never shuts up about their significant other. Often either ignorant of or in denial of the aforementioned partners flaws, the monogamytheist may not even have that good of a relationship with their partner, but treats it like a 60-year marriage.
Omg, Jack never stops talking about all the stuff he and his girlfriend did together, what a monogamytheist!
