Boston slang from Good Will Hunting
Good Will Hunting is NOT about math.
Seriously. If you think this movie is about a janitor solving equations at MIT, you missed the whole point.
It’s about Boston. Loyalty. Class. And how people from Boston actually talk.
I learned this the hard way. I’m Shameem — I learned English in Bangladesh and for years I thought “wicked” just meant evil. Like a witch.
Then I met Emma. She’s from the US and grew up hearing this stuff in Dunkin’ lines and on the T. And she told me, “No, in Boston, wicked means very.”
That one word changed how I understood real American English.
7 real Boston phrases
So today, we’re breaking down 7 real Boston phrases from Good Will Hunting that textbooks will never teach you.
If you say “very good,” you sound like a textbook.
If you say “wicked pissah,” you sound like a local.
Let’s upgrade you.
- Wicked = Very / Extremely
Your new favorite adverb.
Textbook: “It’s very cold outside.”
Boston: “It’s wicked cold outside.”
Use it before any adjective. Wicked smart. Wicked tired. Wicked good.
- Wicked Pissah = Totally Awesome
This is Boston hype. Pure approval.
That party last night? Wicked pissah.
That new car? Wicked pissah.
If you like something a lot, this is how you say it.
- How Do You Like Them Apples?
The ultimate mic drop. The best trash talk in American English.
You use it after you prove someone wrong. You win an argument, you show your result, then — boom. “How do you like them apples?”
Will uses it in the bar scene and the whole theater feels it. It’s not about apples. It’s about winning.
- My Boy / Kid / Chief
This isn’t just a word. It’s loyalty.
In South Boston, you don’t just have friends. You have your boys. When Will says “my boy,” he means “I will ride for this person no matter what.”
It’s ride-or-die English. My boy, my kid, my guy — that’s family.
- Southie / Masshole / Townie
This is Boston identity.
Southie = South Boston. Working-class, tight-knit, proud. Where Will is from.
Townie = Someone who never leaves their neighborhood. Born and raised local.
Masshole = A Massachusetts asshole, usually how they drive. Bostonians say it with pride.
If you understand these, you understand the class tension in the whole movie.
- Bang a U-ey / No Suh / The T
This is how Bostonians actually live.
Bang a U-ey = Make a U-turn. “Bang a U-ey right here.”
No suh = No sir, but fast. Classic Boston dismissal.
The T = The subway. No one in Boston says “metro” or “subway.” It’s always “Take the T.”
You hear this and you know you’re not in a textbook anymore.
- It’s Not Your Fault
The most American emotional English in the movie.
It’s not slang. It’s not funny. But it’s the line Americans actually use when someone is hurting and blaming themselves. It’s real, it’s soft, and it’s powerful.
You don’t say this to be cool. You say this to be human.
We field-tested these on real Americans. Their reaction? “Yo, that’s so Boston.”
Which one are you going to try first?
DEBATE TIME: Do you think Will should have stayed loyal to his boys in Southie, or was he right to leave for the MIT / Harvard future? Drop your take in the comments — let’s argue, Boston style.
