3.
A person that participates in snowboarding, wakeboarding, skateboarding, windsurfing, longboarding, freeboarding, surfing, wakeskating, wakesurfing, skimboarding, kitesurfing, flowriding or any sport that shares similar traits as those listed above. These people tend to be down to earth, and share a special passion for their sport, life and the elements. They can be identified by the clothing they wear usually brand names associated with board sports like Quiksilver, Forum, Billabong, LibTech ect. Boarders lead a laid back lifestyle often forced into doing slave labour so that they can continue to pursue their passion. Often dreaming that one day they will be good enough to be sponsored and be paid to do what they love. When asked to describe their sport they often go on long rants about how amazing and deeply connected they are with everything around them and how the world is a perfect place when they are riding. A very spiritual experience.
There goes a boarder now you can tell because he has some sort of board like device with him/her and the intention to ride it on some gnarly terrain.

1.
A person that Snowboards. They differ slightly from Skaters. They tend to be more in touch with the world and the elements. Wear less baggier jeans, more Brand names such as Quicksilver and O'Neil. Boarders also laze about too much,doing what they want,when they want. Apart from these minor details they look identical to Skaters.
Townies will hate them...

Skater
Boarders are not unlike Skaters. Wearing and doing generally the same apart from being strapped to a board with no wheels at 3000ft.

Australian Definition (girls):

A school aged kid who attends boarding school. They are often stereotyped as being from wealthy families or from large farms. Although many boarders are from these situations, a great deal are also on financial bursaries, and academic/cultural/sport scholarships. Some are just from average families, and their parents have had to make many sacrifices to ensure that their children could receive an education far superior than their own.

Some Aussie kids go to boarding school because they live in remote areas or have poor schooling systems in their area. Many have completed Distance Education.

Boarders in regional boarding schools often affectionately call each other 'bogans' and often dress in trackies, singlets, flannies, thongs and ugg boots. They are world leaders when it comes to wearing their hair in 'messy buns'.

They often use slang and swearing, and are known to be scabs, always trying to get free food off anyone who's got it. They frequently buy fundraiser chocolates.

Socials between boarding schools, "Boarder's Bashes", are extremely popular.

As they enter the senior years, many are taken on leave by day girls to parties involving drugs, sex, alcohol, smokes, and not to mention a video camera to record everthing with. Some of the worst of these will boast of how much they threw up.

They have a terrible habit of 'killing' songs. This means that a girl will play one of the latest songs over and over on their stereo for weeks until everyone decides that they never want to hear it again. Or at least not for 18 months or so. At this moment "Boom Boom Pow" by the Black Eyed Peas is being slaughtered.

Generally they stick together, and are friendly towards one another. They are much more united than day girls,and sometimes day girl vs. boarder fights are ignited.

State of Origin is an important event,and they will passionately wear their maroon and blue to the Dining Hall for the themed Dinner, and then go back to the Common Room to watch the match. Much screaming occurs. (Note: best not to have parents of international students visit at this time. They are slightly scared of both the noise, and the creaking ceiling from the girls jumping up and down upstairs).

The majority of boarders will wear their Boarder status as a badge of pride.

I should know. I am one.
Cassie: So, you like private school?
Patricia: Yep, I love being a boarder!

Ella: Do I look like a bogan?
Kathryn: Yeah, you're a boarder, aren't you?
