Canadian Slang

Canada has two official languages, and this results in a whole lot of slang. 

Here are some examples:

Eh? - Pronounced "ay", used to indicate that you don't understand something, can't believe something is true or if you want the person you are talking to to respond. 

Loonie - The Canadian 1 dollar coin gets its name from the bird on one side of the coin.

Toque - Pronounced "Too-uk", derived from Arabic. It means a cap with a small brim, or without one (in other words, a beanie).

Pop - Soda

Australian Slang

Australians have a unique style of English. With 4300 clipped words in their lexicon, they use more than any other English speakers. Dr Nenagh Kemp from the University of Tasmania is studying why and how these diminutives are created.

"We don't have a lot of information on this really essential part of our language and culture. It sounds obvious, we make words shorter to save us a bit of time and effort. But some diminutives actually make words longer, like Tommo for Tom. And we don't really save a lot of time by saying barbie instead of barbecue. I think we all have an intuitive feeling that these words also make an interaction more informal, more friendly and relaxed.

Dr Kemp is running experiments in which participants either use or don't use diminutives in conversation. The partner then scores them on personality traits to answer the question: Are slang-heavy speakers perceived as friendlier? There is no answer out just yet.

Famous examples of Aussie slang are:

Barbie - barbecue

Roo - Kangaroo

Slab - 24-pack of beer

to whinge - to whine

Irish Slang

The Irish slang doesn't have an interesting article sadly, so I'll just show some examples:

Gob - Mouth

You Dig? - Do you like it?/Do you get me?

Black stuff - Guinness

Jackeen - Someone from Dublin

Mot - Girlfriend

Internet Slang

With the internet being incredibly popular, there are countless amounts of smaller groups on there, which all have their own words and phrases. Some of them catch on and become popular. Here are some examples, and their origin:

AMA - Ask Me Anything, originated from Reddit.com, it refers to a public Q&A. 

DM - Direct Message, from Twitter, it allows you to send a private message to anyone.

ELI5 - Explain like I'm 5, origin unknown. When someone gives you a complicated explanation to something, and you want them to simplify it.

IMO - In my opinion, an internet classic, a way to express your opinion without making it sound like you are telling the universal truth.

IRL - In real life, the internet is virtual life, and when referring to actual life out there this is used.

NSFW - Not safe for work, when you are working you probably wouldn't want to click on a link containing nudity, graphic language or anything offensive. These tags allow you to avoid them.

An interesting fact is that any other slang is mostly spoken, and barely ever written, but internet slang is mostly written and barely spoken.
