The following is a list of Memes and fan-created tropes associated within Monster Musume and its fandom.
General
- Best Girl: A term fans use to refer to their favoured female character. Usually as part of a proclamation of devotion or a rally cry. (eg. "Cerea is Best Girl!")
- Heresy: A type of Monster Musume fan-created image that features a specific character as a completely different species than what they originally were. (eg Rachnera Arachnera as a Centaur, Centorea Shianus as a human). As the fandom orients the character as a representative of their species, to create an image of the character as a different species is jokingly referred as "committing heresy".
Character Specific
Miia
- Snek: The cutesy term "snek" derives from a deliberate spelling mistake in a caption of a photo of an Indian woman holding a giant snake, the popularity of which led to an entire subreddit devoted to images of snakes with and without additional cute interior monologue.
- Roll Me:
- Snake Cloaca: A reference to the fact that while she may behave and be able to interact just like a human, Miia's lower body (and by assumption, her genitalia) is serpentine. Meaning that if a devoted fan wished to sleep with her they would be interfacing their human-half with her bestial-half and committing pseudo-bestiality during intercourse. This reference is jokingly made by character-haters when listing the character's undesirable features.
Papi
- Birp:
- Bird Cloaca: A reference to the fact that while she may behave and be able to interact just like a human, Papi's lower body (and by extension, her genitalia) is avian. Meaning that if a devoted fan wished to sleep with her they would be interfacing their human-half with her bestial-half and committing pseudo-bestiality during intercourse. This reference is jokingly made by character-haters when listing the character's undesirable features.
Centorea Shianus
- Horse Pussy: A reference to the fact that while she may behave and be able to interact just like a human, Centorea's lower body (and by extension, her genitalia) is equine. Meaning that if a devoted fan wished to sleep with her they would be interfacing their human-half with her bestial-half and committing pseudo-bestiality during intercourse. This reference is jokingly made by character-haters when listing the character's undesirable features and has gone on to be used in reference to other centaur characters.
Suu
- Does this look like the face of mercy?: A reference to Suu's constantly empty and innocent expressions in contrast to her aggressive "anytime, anywhere" attacks on anybody covered in water when she is thirsty. As she continues her attacks until her "prey" is dry regardless of their protests and attempts to stop her; often leaving them dazed and weak from orgasming under her sexual domination, she is considered by the fandom to be "without mercy".
Meroune Lorelei
- Murder Fish:
Rachnera Arachnera
- Loli Rachnera:
- Spooder: A cutesy term used in reference to spiders.
- Caffeinated Spider:
Lala
Other
- Everyday Life With Bicycle Cop: A fan-created scenario where the Bicycle Police Officer had his own band of house stay girls.
- TTF Loves Polt: A meme that arose in 4chan following the revelation that one of the resident fan translators (TanktopFag) preferred Polt as his favourite character. Learning of this, Okayado would later make TTF appear in Chapter 43 as one of the sportspeople in Polt's gym.
- Touch the Cow, Do it Now!: A phrase first found in a children's picture book detailing farm animals.
- Polt Gyat:
