Republican presidential candidate Donald Trump may think his raunchy comments about grabbing women were "locker room banter," but professional athletes who spend countless hours in locker rooms beg to differ.

Scores of athletes have condemned Trump and ask where is this mythical locker room where men talk the way he does.

"Sure, guys sometimes talk about conquests and those types of things," former National Football League quarterback Sage Rosenfels told Time magazine.

"But the guys who did that were usually thought of as the more immature players, the players who didn't get much respect.

"Plus, there's a distinction between raunchiness and bragging that you grope women without their consent."

Portland Trail Blazers basketball guard CJ McCollum also told Time: "We talk about a lot of stuff in the locker room. We don't discuss assault."

The Kansas City Chiefs football team's wide receiver Chris Conley agreed that the subject of "girls" comes up – but not that way.

Los Angeles Galaxy soccer midfielder Robbie Rogers was annoyed that Trump was using his stomping ground as an excuse.

Cleveland Cavaliers basketball forward Dahntay Jones said the implication was that calling Trump's comments "locker room banter" made them acceptable. "They aren't," he tweets.

Olympic hurdler Queen Harrison said linking bad behaviour to a locker room in no way made it OK.

UFC mixed martial artist CM Punk (Phillip Jack Brooks) seemed particularly offended by Trump's comments, calling them not locker room banter but something American serial killer Ted Bundy would say. "It's a Ted Bundy quote," he tweeted.

Atlanta Falcons tight end Jacob Tamme was glad for locker room showers.
