If we've said it once, we've said it a thousand times: everyone hates Carlos Boozer.

In this case, "everyone" includes Portland Trail Blazers center Joel Przybilla, who has had a series of run-ins with the Chicago Bulls forward over the years.

Another such incident took place during a fourth quarter rush for a loose ball during Friday night's game at the United Center. As Bulls guard C.J. Watson and Blazers guard Nolan Smith tussled for control, resulting in a jump ball, both Boozer and Przybilla hit the deck, with Boozer catching Przybilla with an elbow during the scrum.

Przybilla took exception immediately, as he is wont to do, and was captured by cameras requesting that Boozer consider extending their mix-up following the game.

"Meet me after, meet me after, I'll f*** you up," Przybilla appeared to yell at Boozer. Boozer shook off the comment and walked back to the Bulls bench.

The Blazers went on to upset the Bulls 100-89, earning the first career victory for Kaleb Canales, Portland's interim coach, who took over for Nate McMillan after he was fired on Thursday. 

Here's video of the profane exchange between Joel Przybilla and Carlos Boozer, which involved Przybilla challenging Boozer to a post-game fight.
