Festival organisers are determined to put the clamps on the ‘roid muscle culture’ this year with next month’s Goodlife event the first to lay down the law.

The underage occasion at Sydney’s Randwick Racecourse has implemented a dress code which reads ‘No bum bags / fanny packs and shirts must remain on at all times except for in the water park.’

The policy stems from reveller backlash after an ugly brawl marred last year’s Stereosonic in the Harbour City.

The ‘shirts on’ policy has been in existence for a few years at some festivals but it will be strictly enforced from this year with topless patrons set to be ejected.

Sterosonic co-founder Frank Coletta vowed to stereotypically ‘profile’ jacked-up bullies out of his hugely popular festivals.

“Everyone is laughing at your shorts, singlets, fake tans, bum bags and cartoon-shaped bodies … but more importantly we are sick of the charged-up violence you bring and it’s time for a change!” he wrote on his Facebook page.

News of the policy has sent some body building forums into meltdown and only time will tell as to whether the bros can bare the subsequent drop in ‘mirin’ levels.

It remains unclear which, if any, outfits for women will be affected.
