세계의 슬랭 안내서

Every language has two lives: the version that shows up in textbooks, and the version that actually gets spoken on the street, in group chats, and across bar counters. Slang Words Online exists for the second one. We built this site as a slang words hub for anyone who has ever overheard a word in conversation, in a song lyric, or in a subtitle and thought: what on earth does that mean? Whether you are trying to decode British slang picked up from a London pub, American slang that keeps showing up on social media, or Australian slang your co-worker drops without a second thought — the answer is here, explained with the kind of context a translation app will never give you.

Our slang words library currently covers sixteen countries and eleven topic categories. You can browse British Slang and American Slang alongside Australian Slang, Canadian Slang, and Irish Slang — the big branches of the English-speaking world. Then there are the Romance-language collections: Mexican Slang, Spanish Slang, Italian Slang, French Slang, Colombian Slang, Cuban Slang, and Dominican Slang, each reflecting a distinct dialect with its own rhythm and attitude. We also cover German Slang, Russian Slang, Japanese Slang, and Korean Slang — four vocabularies where the distance from the textbook version is large enough that slang almost functions as a separate register.

What makes this collection different from a quick Google translate? Depth, mostly. Every entry includes the definition — often more than one, because slang words rarely mean just one thing — alongside a pronunciation guide that covers how the word actually sounds, not how it ought to sound. We provide worked examples: full sentences in the original language, translated line by line, so you can see the word doing its job in a real context. And we tell you the things that matter most and that dictionaries usually leave out: whether the word is affectionate or hostile, whether it is safe for mixed company, and whether the cute origin story everyone shares on the internet is actually true.

The topics are organized the way people actually search. Instead of dumping hundreds of entries on one page, we split them into categories that reflect what slang is for: Slang for Approval & Praise, Slang for Greetings & Address, Slang for Insults & Complaints, Slang for People, Slang for Money & Work, Slang for Food & Drink, Slang for Going Out & Partying, Slang for Romance & Flirting, Slang for Emotion & Reaction, Slang for Filler Words, and Slang for Everyday Things. Each of those lives under a specific country, because the same subject — money, say, or insults — produces completely different vocabulary depending on who is speaking and where.

This site is free to use, regularly updated, and available in nine languages so non-English speakers can navigate the whole library in their own language too. Think of Slang Words Online as the slang words library you always wished existed: thorough, honest, and written by people who actually care whether you embarrass yourself at the wrong moment. Dive in — pick a country, pick a topic, or just search for the word you heard.
