If you’re a guy who puts your “bros” above everybody else, the Pepsi Max Australia ‘Top Mates’ challenge is the perfect way for you to capitalize on that.

The Pepsi Max Australia ‘Top Mates’ challenge is an online social media campaign targeted at males in their 20s. Created in conjunction with advertising agency Clemenger BBDO Sydney, it asks men to visit the Pepsi Max Australia Facebook page and download a smartphone app that will allow them to imitate “bro-fists” at check-ins, says Popsop. Users make their own “bro profile,” add their friends (those with whom they typically hang out), and then use the bro-fists to earn points and badges for spending the most time with their friends. Participants who check-in the most—i.e. those who spend the most time with their buddies—get a chance to win a $30,000 “bro-cation.”
