The trash talking between the Los Angeles Clippers and Golden State Warriors has started -- even before their first-round playoff series became official late Wednesday night.

Earlier in the day, Warriors guard Klay Thompson called Clippers forward Blake Griffin out for flopping and playing "kind of out of control sometimes."

"He is a good guy off the court but he probably just ... I mean ... plays pretty physical and flops a little bit," Thompson told The Wheelhouse on 95.7 The Game radio in San Francisco.

"He flairs his arm around so you know you might catch a random elbow or something that doesn't you know rub off too well on guys," Thompson said. "He's kind of like a bull in a china shop, kind of out of control sometimes. And then you do just see him flop sometimes like how can a guy that big and strong flop that much.

"I can see how that gets under people's skin and be frustrating to play against."

The bad blood between the Clippers and Warriors has been brewing over the past two seasons. The teams will open the postseason against each other on Saturday at Staples Center.
