The first chorus of boos came with 14:23 left on the pregame clock when the Los Angeles Lakers jogged onto the court at Chesapeake Energy Arena before Game 1 against the Thunder.
During pre-game introductions, the boos got personal and never left the intended target of Lakers forward Metta World Peace the rest of the night.
As expected, World Peace got an earful Monday night from a sellout crowd of 18,203 at The Peake.
The treatment stems from a vicious elbow World Peace planted on the left side of James Harden's face on April 22 at Staples Center.
Harden missed the final two regular-season games with a concussion. World Peace was suspended for seven games.
World Peace was booed every time he touched the ball, shot the ball, passed the ball, rebounded the ball, dribbled the ball, left the game, re-entered the game and especially when he fouled.
The longer the game went, the less World Peace's presence mattered as the Thunder embarrassed the Lakers with a 119-90 rout.
Cheers for the home team were far more prominent than boos for World Peace, who finished with 12 points, two rebounds, two assists, one steal and two fouls.
Harden finished with 17 points, two steals and two rebounds in 24½ minutes.
The longest and loudest cheer of the night came three minutes before tipoff when Harden was presented his trophy for Sixth Man of the Year.
The standing ovation was so deafening, the PA announcer's introduction for Harden could barely be heard.
During pre-game introductions, 10 seconds of booing for World Peace drowned out the entire intro for center Andrew Bynum.
To a resounding chant of “Beat L-A,” the ball was tipped.
The first time World Peace touched the ball, he converted a 3-pointer.
The second time he touched the ball, he had a nice touch pass to Bynum for a dunk.
The third time World Peace touched the ball, he hit another 3-pointer.
After that was a whole lot of not much.
There were shifts where Harden defended World Peace, and vice versa.
Harden went to the floor when he was fouled hard by World Peace.
With 7:02 left in the third quarter, World Peace grabbed Kevin Durant at the waist to prevent and easy basket.
