Only four-letter words are fit to describe a defeat like this.

No, not rout.

Worse.

Quit.

The Nets took a 130-77 beating at Little Caesars Arena in Detroit on Sunday.

And worse than the final margin was the meekness.

“It’s not just that you don’t play consistently hard: It’s that you quit. And we cannot allow that,” coach Jordi Fernández said.

“So, it starts with me; gotta create habits … So obviously this one hurts. Got to help them be better.”

It would be hard for them to be worse.

Except, well, they have been.

There was the 54-point loss to the Knicks on Jan. 21, the second worst in team history.

Then a 37-point caning against the Clippers to start this road trip.

Now a 53-point embarrassment to end it.

“Man, we just got to learn from it,” said Nic Claxton, who had 10 points in the first quarter, and was scoreless after that. “We just can’t keep getting beat by 50, though. It’s really demoralizing as a group for us. We got to come together and figure out ways to at least keep the games closer.”

With Michael Porter Jr. out for personal reasons, the Nets embarrassed themselves.

They shot just 32.9 percent and 7-for-31 from deep, bullied by a physical Detroit defense.

And they were just as bad on the other end.

The Nets let the Pistons waltz up and down the court, turning 25 turnovers into 39 points.

Much of that Nets sloppiness came in a crippling 47-12 run that spanned halftime and turned a 33-32 deficit into a huge 80-44 hole.

Brooklyn shot 4-for-20 in that blitz with 10 turnovers.

No Net managed more than a dozen points, with Cam Thomas and Drake Powell sharing team-high honors off the bench.

Jalen Duren had 21 points and 10 rebounds for Detroit. Cade Cunningham added 18 points and a dozen assists.

“We found ways to get good shots early on; and we couldn’t match that. And then it was from frustration to whatever you want to call it is forgetting what you’re supposed to do,” said Fernández. “So we’ll run it back. We’ll hold them accountable, we’ll give them a hug, whatever the case may, just (we have to) go out there and play better than this.”

The only silver lining was the Nets (13-35) moving into a tie with Washington for fourth in the lottery race. They’re a half-game behind third-place Indiana and a game ahead of Utah.

Porter missed a second straight game after the death of his grandmother.

Noah Clowney missed a fifth straight game, with an MRI revealing a lower back sprain.

The NBA honored Chuck Cooper, Nat “Sweetwater” Clifton and Earl Lloyd breaking the color barrier in 1950.

“Instead of using ignorance and lack of understanding for others to separate people and divide people, I think this is a great opportunity for us to understand that the more we learn about one another, the more we recognize that we’re not as different as people would want us to be,” said JB Bickerstaff. “I think that would eliminate a lot of the problems that you’re seeing unfold in front of us.”
