Things have gotten testy in the second-round series between the Dallas Mavericks and Phoenix Suns. Luka Doncic certainly doesn't sound like he's ready to make friends with his opponents.

After the Game 5 shellacking that the Suns dished against Dallas, Luka Doncic was recorded walking into the locker room. The Slovenian superstar had some rather spicy words against the home team on Tuesday.

“Everybody acting tough when they up,” said the Mavs star not once, but twice.

There were a handful of dust-ups throughout the one-sided affair that could have led to tempers flaring on the Mavs side. Devin Booker casually mocked Doncic during one play in which he pretended to be hurt after a baseline foul. There was also an attempted rendezvous in the locker room tunnels between Mavs' Marquese Chriss and Suns' Bismack Biyombo that did not look like the makings of a friendly meet-up.

The Mavs were run off the floor in the second half and are now one game away from elimination. They're clearly in no mood to just ignore any fighting words being hurled their way.

With the series shifting back to Dallas, look for Luka Doncic and Co. to try and return the favor on the basketball court. Here's to hoping the heated action doesn't extend beyond the friendly confines of the hardwood.
