London slang: what you hear on the streets

If you’ve ever walked through Camden, Shoreditch or a Tube carriage, you’ve probably heard words that sound odd if you’re not from the city. London slang isn’t a secret code, it’s just the way locals shorten phrases, add humour or show where they grew up. Knowing a few of the most common terms can make you sound like you belong, help you understand jokes, and avoid awkward misunderstandings.

Common words and their meanings

Peng – Something that looks great or is attractive. “That new coffee shop is peng.”

Mate – A friendly way to address anyone, not just a close friend. “Alright, mate?”

Bob’s your uncle – Used to say “there you go” after a simple instruction. “Just add the sauce, Bob’s your uncle.”

Taking the mickey – Making fun of someone or teasing. “He’s just taking the mickey, don’t be offended.”

Gutted – Very disappointed. “I missed the concert, I’m gutted.”

Proper – Used for emphasis, meaning “really” or “genuine”. “That was a proper good night out.”

Cheeky – Describes something a bit bold but in a fun way, like a “cheeky pint” after work.

Wicked – Something excellent or exciting. “The new album is wicked!”

Sorted – Means a problem is solved. “Don’t worry, it’s sorted.”

Faff – To waste time or be indecisive. “Stop faffing around and get going.”

How to use them naturally

First, listen. The best way to pick up slang is to hear it in context—watch local YouTubers, listen to radio shows, or just eavesdrop in a café. Next, start small. Slip one word into a sentence when you’re confident, like saying “That’s a proper good idea” instead of “That’s a great idea.”

Don’t over‑do it. Dropping a slang term every other sentence can sound forced. Use it where it fits naturally, especially when you’re relaxed with friends or in informal settings. If you’re in a professional environment, stick to standard English—most workplaces still prefer clear communication.

Watch your tone. Some words, like “mate”, can sound rude if you say them sharply. Keep a friendly, relaxed tone and you’ll likely be understood as polite. Also, regional variations exist: a “tonic” (meaning a cheap bottle of alcohol) might be used more in East London than in Westminster.

Finally, be ready for correction. Londoners love to correct misuse, and they’ll usually do it with a laugh. Take it as a learning moment—say “cheers for the tip!” and you’ll be on your way.

Now you’ve got a toolbox of the most common London slang. Try them out next time you’re ordering a coffee, chatting on the Tube, or meeting new friends at a pub. Before you know it, you’ll sound less like a tourist and more like a local who knows the city’s rhythm.
