(Especially) when they are accompanied by one or more friends and they are drinking, they can be quite loud, arrogant, mouthy, disrespectful and belligerent. This way they are the Anglo/European counterpart of a Lebo boofhead gang-member.
Their insular mindset means they will hate on anyone who they haven't known since they were in primary school and those who have some sort of life outside footy and collecting benefits, referring to them all as faggots.
The worst ones usually the older ones who have given up playing footy long ago but are still attached to their shitpot suburban footy club for the booze nights, the illegal substances and because they can't make friends anywhere else due to their insular mindset, their obnoxious personalities, their amphetamines-induced psychosis and paranoia and their lack of any intelligence.
The younger teenaged ones are smartarses who hide behind their older friends' backs when it looks like they are going to be brought to account for their disrespect, they are apprentice scumbags.
There are many good people who play footy but these wankers are destroying the image of Aussie Rules. They should all be sent to Macquarie Island where they can bash and inbreed themselves out of existence and out of sight of the human race.
