Like any community, cosplay has a lingo all its own filled with quirky expressions and shorthand that can feel like an entirely different dialect for a newbie.
Let’s unravel the cosplay lingo and break down what these popular phrases really mean.
And of course, I don’t know ALL the terms, as some areas may have their own twist on things. So, feel free to leave your own suggestions in the comments! I’ll also update the list as I think of new words to add.
Cosplay Lingo Defined
Con Crunch
This infamous term describes the stressful, often sleepless rush to finish a costume just before a convention. Whether it’s late-night sewing marathons or last-minute hot glue chaos, con crunch is a rite of passage almost all cosplayers will experience at some point.
Con Crud
Con crud is what you get after attending an event filled with tons of people and all their germs. After the con you might come down with a cold or feel unwell. It’s very common and almost always happens to me after DragonCon.
Try to remember to wash your hands and use hand sanitizer to cut down on the possibility of getting the crud.
Foam Brain
Spend enough hours shaping EVA foam into armor, and you’ll get it—foam brain hits when your brain goes on autopilot after too much crafting. You start using heat guns like hairdryers and question if you’ve eaten anything besides coffee and granola bars in the past 48 hours.
EVA Foam
While not a slang term, it is a word you will hear a lot! EVA foam is a soft, flexible, and durable material often used in crafting armor and props. EVA stands for Ethylene-Vinyl Acetate.
Worbla
Worblas Finest Art is the full name of this type of thermoplastic, and it is often used to make intricate armor pieces. However, Worbla is a good deal more expensive than EVA foam.
Worbla is heated and molded, and every scrap can be reheated and remolded, which makes material waste minimal. Many people use a combination of Worbla and EVA foam to make cosplays.
Closet Cosplay
This is a cosplay created by items you already have in your closet. Often a more casual version of a character, or a look more on the “inspired” side.
Canon vs. Fanon
“Canon” refers to the official story or design of a character, while “fanon” means ideas embraced by the fandom but not part of the original material. A fanon costume might give Sailor Moon a steampunk twist or dress Darth Vader in a kimono.
DTF
Contrary to what you may see this acronym being used for in other capacities, in cosplay DTF often refers to Direct to Film printing and can be used to recreate detailed graphics for costumes.
Unlike Direct-to-Garment (DTG), which works best on cotton, DTF products like the ones from bestpricedtf.com work on cotton, polyester, nylon, treated leather, and other fabrics often used in cosplay creation.
Rule 63 and Genderbend Cosplay
This one’s a nod to internet lore: if a character exists, there’s a version of them with their gender swapped. Also referred to as a genderbent cosplay, but not to be confused with crossplay.
Crossplay
Crossplay is when someone dresses as a character of a different gender. It’s all about embodying the character, no matter their gender identity, and is embraced widely across the cosplay community.
Cosplay Mashup
Why choose one fandom when you can combine two? A cosplay mashup blends characters or styles. Think “Sailor Jedi” or “Batman Hogwarts Student.” It’s a playground for creativity and a big hit on the con floor.
Post-Con Depression
Sometimes after spending several days at a con, the high of the excitement wears off and leaves you feeling a little down. This is post-con depression, and it is a real thing. But don’t despair! There is always another con on the horizon.
Armor Envy
A joking term for the awe and mild jealousy you feel when you see someone’s perfectly crafted costume, especially when their armor looks like it was forged by elves—or a 3D printer wizard.
Hall Cosplay
These are lighter, more comfortable costumes worn to casually walk around a con—perfect when you want to be part of the fun but still eat, sit, and survive a full day indoors.
Cosplay Community Language
There are probably many more cosplay related terms to cover, but this is a good list to get you started!
Cosplay slang is more than just playful language—it’s a snapshot of the humor, passion, and shared experience that define the community. Learning the lingo comes with experience.
So next time you hear someone say they’re deep in con crunch or suffering from foam brain, just nod, offer snacks, and remind them: the cosplay may not be done yet, but they’re doing it right.
