Your group of mates, usually the lads you roll with. Basically your crew.
I'm linking the mandem later to watch the match.

bogan
Someone seen as rough around the edges and unsophisticated, kind of like a British chav or an American redneck. It can be a put-down, but plenty of people use it fondly or even call themselves one.
Mullet, flanno and a ute with a massive sound system, he's a proper bogan.
wasteman
A wasteman is a useless, unreliable or clueless person, usually a guy, the type you can't count on for anything. If it's a girl, people say 'wastegal'.
He said he'd pay me back last month and still nothing, proper wasteman.
