Why is BMO called BMO?

Football refers to BMO with male pronouns and herself with female pronouns, according to their first introductions to each other ("real baby girl" and "little living boy" respectively) despite BMO being genderless.

Canonically, BMO has no gender and is referred to throughout the show by both masculine and feminine pronouns. They take on hyper-masculine and -feminine traits during different storylines, but for the most part could be considered agender.

"The Lich" is referenced in dozens of episodes throughout the show, and the presence of death itself proves to be the scariest thing of all.Nov 9, 2021
