The alphabet of our world

The words behind the letters

Age Play. The umbrella term for consenting adults who, as part of play, scene, or scenario, choose to take on an age different from their real one. It's intentional, it's consensual, and — for many — it's deeply freeing.

Age Regression vs. Age Play. These get used interchangeably, but they're not quite the same. Age regression is usually internal — an involuntary or psychological slide to a younger head space that feels genuine. Age play is the deliberate, consensual doing of being a different age, complete with props and scenarios. Most people fall somewhere on a blend of both.

Little. Someone who likes to lean into acting younger than their actual age. "Little" is a wonderfully broad spectrum — it can span anything from a few months old to preteen, depending on the person and their head space.

Role Play. The bigger tent that age play lives under. Role play is where consenting adults recreate scenes from a younger (or older) age — often from infancy up to around age 20, though it's certainly not limited to those years. People often use props to help sink into the experience: age-specific clothing, furniture, toys, or other objects that help them slip into that younger head space.

Little Space / Big Space. "Little space" is that place you go when you're fully in your younger head space — playful, soft, carefree. "Big space" is your everyday adult mode. Being able to name the two helps partners and caregivers know where you are (and when it's time to ease back out).

Head Space. The mental state behind all of this — the shift where a scene or role stops feeling performed and starts feeling real. It's what most people are chasing when they curl up with a stuffie or slip into gear.

Munch. A casual, vanilla public meetup (coffee shop, restaurant) for the community to hang out — no play, no gear, no vetting. The classic "come say hi and meet real people" event.

Stuffie. A stuffed animal (plush pal). Part comfort object, part faithful companion, and an absolute essential on many a little's couch.

Switch. Someone who can comfortably move between roles — like being a little sometimes and a caregiver other times, or a top/bottom dynamic. There's no rule that you have to pick one side.

Gear / ABDL Gear. The physical side of the scene: diapers, onesies, bottles, pacis, footie pajamas, bibs, toys — the props that help set the scene and bring that head space to life.

Vanilla. A term for "mainstream," non-kink-friendly things. A vanilla munch = a totally ordinary public meetup. Vanilla is a good thing in this community; it's not a put-down, just a way to describe the plain-and-normal side of things.

Regression (Psychological). This is the one that gets felt more than spoken. It's an experience where an adult feels their sense of age actually reverses — sliding back to a younger state that shows up in their emotions, perceptions, and activities. For many, it doesn't feel performed or forced; it feels real and natural, as genuine as any other part of them.

One last thing

There's no test, and there's no wrong way. Labels are here to help you find your people, not to lock you in. You might land on a word that changes next year, or a mix that doesn't fit any single box. That's normal, and that's welcome. So lurk, ask, try a munch, and let yourself learn at your own pace — the alphabet gets a lot friendlier once you're using it with people who get it.
