South Park has waded into the controversial issue of transgender athletes in its latest biting satire.
Titled 'Board Girls', the seventh episode of the 23rd season focuses on a character called Strong Woman entering a Strongwoman Competition, an event she has previously won.
But she faces strong competition from Heather Swanson, an extremely large and hairy biological male resembling late wrestler 'Macho Man' Randy Savage.
Swanson claims to be a transwoman, even though they've only been identifying as a female for a few weeks.
"I'm not here to talk about my transition, I'm here to kick some f**king ass," Swanson says.
"Let me tell you something... I'm gonna roll up the other women here, and I'm gonna smoke 'em. I am the strongest woman this state has ever seen!"
Swanson wins the competition, but it's revealed at the end of the episode he's actually an ex-boyfriend out for revenge against Strong Woman.
However it's led to a backlash from transgender activists against South Park creators Matt Stone and Trey Parker.
Transgender world track cycling champion Rachel McKinnon criticised the episode on Twitter, calling it "transphobic" and "lazy".
"South Park has been deeply transphobic the entire time," she wrote.
"This isn't their first explicitly transphobic story line. It won't be their last. Stone and Parker are transphobes. Write them off. Ignore their lazy show."
