New York City has its own language that sets locals apart from tourists and transplants. From the subway platforms to the corner bodegas, you’ll hear words and phrases that might leave outsiders scratching their heads.
These slang terms reflect the city’s rich cultural mix, blending influences from Hip-Hop, Yiddish, and decades of neighborhood storytelling into everyday conversation.
1. Deadass

When a New Yorker says “deadass,” they mean business. No exaggeration, no playing around, just pure, unfiltered honesty.
You might hear someone drop this word when they’re making a point they really want you to believe. It’s also thrown around as a one-word response to confirm something is totally true.
Picture someone refusing to overpay for a slice of pizza and saying, “I’m deadass not spending fifteen bucks on that.” The term captures that signature New York directness, where people say exactly what they mean without sugar-coating anything.
2. The City

Ask a Brooklynite where they’re headed this weekend, and they might say “The City”, but they’re definitely not talking about Brooklyn. To real New Yorkers, “The City” means one place only: Manhattan.
Whether you live in the Bronx, Queens, Staten Island, or Brooklyn, crossing over into Manhattan is always described this way. It’s a linguistic quirk that instantly reveals who grew up here.
Tourists might find it confusing since technically all five boroughs make up New York City, but locals have used this term for generations to distinguish Manhattan from everywhere else.
3. Mad

Forget using “very” or “really”, New Yorkers just say “mad” to intensify almost anything. That new restaurant? Mad expensive. The subway ride? Mad crowded.
This word works like a volume knob for descriptions, cranking up whatever you’re talking about. Someone might tell you a concert was “mad good,” meaning it totally exceeded expectations.
The beauty of “mad” lies in its simplicity and versatility. You can apply it to feelings, quantities, or qualities, and every New Yorker will instantly understand exactly how much emphasis you’re adding to your statement.
4. Schmear

Walk into any authentic New York bagel shop and order a “schmear,” and you’ll get a thick, generous layer of cream cheese slathered on your bagel. This Yiddish-derived word has become bagel vocabulary 101 for locals.
The term perfectly captures that unapologetic abundance New York delis are famous for, none of that sad, thin spreading you might find elsewhere.
Whether you prefer plain, scallion, or vegetable cream cheese, asking for a schmear signals you know your bagel etiquette. It’s one of those delicious linguistic remnants from the city’s Jewish immigrant communities.
5. Brick

Winter in New York hits different, and when the temperature drops to bone-chilling levels, locals have one word for it: brick. Not just cold, brick cold, as in solid, unforgiving, and impossible to ignore.
You’ll hear this warning before stepping outside on those brutal January mornings. “Yo, it’s brick out there, grab your heavy jacket!”
The term vividly captures that specific kind of cold that feels like walking into a brick wall. It’s the weather that makes you question why anyone chooses to live somewhere with such harsh winters, yet somehow New Yorkers wear it like a badge of honor.
6. Yerrr

“Yerrr!” echoes across New York streets as the ultimate multi-purpose greeting. It’s louder and more energetic than a simple “hey,” carrying that unmistakable New York attitude.
This evolved form of “yo” serves as a way to get someone’s attention, say hello, or express excitement all at once. You might shout it across the block when you spot your friend.
The pronunciation stretches out the sound, making it impossible to ignore. It’s particularly popular in the Bronx and has spread throughout the city’s Hip-Hop culture, becoming a signature sound of New York street communication.
7. Pie

Mention “pie” anywhere else in America, and people think dessert. Say it in New York, and locals know you’re talking about an entire pizza, the real deal, not just a single slice.
This linguistic shortcut reveals your insider status immediately. When you’re feeding a group or just really hungry, you skip the slices and order a whole pie.
New York’s legendary pizza culture earned this special terminology through decades of perfecting thin-crust perfection. The word connects back to the circular shape and the pride New Yorkers take in their pizza traditions, which they’ll defend against any other city’s claims.
8. On Line

Here’s where New York grammar gets weird: locals stand “on line,” not “in line” like the rest of the country. It sounds strange to outsiders, but it’s deeply ingrained in how native New Yorkers speak.
Whether waiting for concert tickets, a trendy brunch spot, or the subway turnstile, you’re always on line. The preposition choice marks a clear linguistic boundary between locals and everyone else.
Language experts have traced this quirk back generations, though no one’s entirely sure why it stuck around specifically in the New York area. Regardless of its origins, using “on line” instantly broadcasts your hometown credentials.
9. Son / Kid

“Yo son, you coming through later?” In New York, calling someone “son” or “kid” has nothing to do with actual family relationships or age. These terms serve as casual, friendly ways to address pretty much anyone.
You’ll hear it between friends, acquaintances, or even strangers in conversation. “Relax, kid, everything’s cool” might be said to calm someone down, regardless of how old they are.
These terms of endearment emerged from the city’s Hip-Hop culture and neighborhood bonds. They create instant familiarity and reflect that unique New York blend of toughness and brotherhood that defines how people connect on the streets.
10. Frontin’

Catch someone pretending to be something they’re not, and a New Yorker will call them out for “frontin’.” This term exposes fake behavior, whether someone’s showing off borrowed wealth or putting on an act for attention.
“He’s all dressed up in designer gear, but he’s just frontin’ for Instagram.” The word cuts through phoniness with typical New York bluntness.
Authenticity matters in a city where people can spot a fake from a mile away. Frontin’ describes that performance people put on to impress others, and calling it out is part of keeping things real in New York’s no-nonsense culture.
