As each housemate raced to thaw their ice blocks and win the advantage, fans’ minds wandered to a rather risque place.
Vigorously rubbing the frozen stacks, fans quickly pointed out the questionable motion.
“The editing of this challenge is top notch,” one Twitter user commented, while another wrote: “Daniel with that up and down hand motion.”
The competition came down to the pointy end of their icicles with newcomer Garth and AFL star Daniel battling it out to release their flag.
“Daniel looks like he has quite a bit of experience with that hand motion on the ice,” a third Twitter user wrote.
“It’s just two guys stroking their flags,” another added.
At one point, Daniel even tried to thaw his ice block by urinating on it - but in the end, stage fright got the better of him.
While we doubt it was the intention of Big Brother’s production team to create such an eyebrow raising challenge, it had many fans comparing it to the show’s raunchy spin-off Big Brother Uncut.
“I thought this was Big Brother uncut for a second,” one viewer commented.
“Daniel peeing on the ice is the closest we’ll get to Big Brother uncut,” another wrote.
The original show was known for it’s uncensored dramas (who could forget the “dancing doona”) and its risqué spin-off Uncut.
Since there’s no plans to revive the late-night show with Channel Seven aiming for more family friendly viewing, fans will have to relish these borderline moments.
