10 Online Slang Dictionaries to Learn Jargon and Street Language

Saikat Basu 12-10-2010

Even Shakespeare used slang. A simple internet search reveals that. It’s a different story that his lingo influenced most of the English language.


That’s the story with a lot of street-speak and jargon. Slang words don’t mind that they are not a part of Webster’s or Roget’s. It is just a matter of time before they get hauled up from the streets and into the pages of a regular dictionary. But for every word that becomes a part of the dictionary, there are many more that stay behind.

There are some we know and say each day. Then there are some which leave us befuddled. For vernacular language is also about generations. Each age has its own. Today, even the online world of chat and Twitter has its own unique set of jargons. Maybe you will ask someone the meaning directly. Maybe you will just nod in presumed understanding. Maybe you will take the help of the web.

In the last case at least, let these ten slang dictionary websites help you to look up slangs and jargons that are the order of the day.

Urban Dictionary

“˜Defenestrate’ is a word Microsoft won’t include in its dictionary. I found out these days it means to uninstall software from a Microsoft operating system, usually in frustration. Actually, it’s a proper English word; Urban Dictionary just gave it a funny turn. Well, that’s what it does – in an accurate though humorous way. But it also takes a practical look at the words that gets bandied about in mainstream media and the streets. Urban Dictionary is a user generated online word resource.

So expect to find usage notes and translations of all kinds here.

I thought that “˜rainmaker’ referred to the Red Indian who could appease the rain gods. In corporate jargon though, it’s the guy who makes the company a lot of money. Unsuck It is a searchable database of words spoken around water coolers, cubicles, and boardrooms.

    Rap is itself only comprehensible as Nihilism dressed up in fake African ethos.
    Logically, therefore, the slang "language" associated with rap is likeliest to be at best incomprehensible to any person with an IQ over 120.

      We might deride it, but as long as a portion of the population speaks it and it's a part of our pop-culture, we cannot ignore it:)

      I found the Rap Dictionary toughest to comprehend. The language is beyond me :) Urban Dictionary is definitely the coolest.
