A US radio host is being slammed for saying 17-year-old American gold medal snowboarder Chloe Kim is a 'little hot piece of a**'.

Barstool Radio's Patrick Connor made the sexual remarks about the underage Olympian on Tuesday after Kim took out the gold medal in the women's halfpipe in Pyeongchang.

Connor, who is co-host of Barstool's new Sirius XM talk show Dialed-In with Dallas Braden, was speaking with ex-baseball pitcher Dallas Braden and comedian Brody Stevens at the time.

After the trio joked about how Kim's name was similar to Kim and Khloe Kardashian, Connor shockingly said he was counting down the days until the teen snowboarder's 18th birthday in April.

Connor went on to compare himself to Matthew McConaughey's character in the film Dazed and Confused.

'Her 18th birthday is April 23 and the countdown is on baby because I got my Wooderson going. "That's what I like about them high school girls",' he said.

'She's fine as hell!' Connors added while his co-hosts laughed.

'If she was 18, you wouldn't be ashamed to say that she's a little hot piece of a**. And she is. She is adorable. I'm a huge Chloe Kim fan.'

Deadspin first reported on Connor's demeaning comments and the radio host's only response to the criticism was a tweet that read: 'Deadspin still exists?'

The Californian teen became the youngest woman to win a gold medal on snow at the Winter Games after dominating the women's halfpipe snowboarding final on Tuesday.

She is also the first woman born in the 21st century to win a gold medal at the Winter Olympics.

Kim put up a score of 93.75 on the first of her three finals runs and then bettered it with a near-perfect 98.75 on her last run with the gold already well in hand.

She hit back-to-back 1080-degree spins on her second and third jumps - repeating a combination no other woman has ever done in a competition.
