J-E-T-S! = J-A-I-L!

A rabid Jets fan ticked off the wrong person — an off-duty San Diego cop — by loudly cheering his team’s playoff upset Sunday against the Chargers.

In what has become a YouTube sensation, several San Diego officers are seen roughly handcuffing New York native Bill Carroll for allegedly being drunk and resisting police.

Carroll — who had been shouting “J-E-T-S, Jets! Jets! Jets!” near the off-duty officer — told The Post yesterday, “I wasn’t doing anything wrong. I was just watching the game.

“What’s wrong with me saying, ‘Jets, Jets, Jets?’ ”

He said he had just three beers over four hours and cops refused to let him take a Breathalyzer test to prove he was sober.

The officers “were just totally out of line, and they wouldn’t listen to reason,” said Steve Sevigny, a Charger fan who witnessed the arrest.

“The poor guy was just totally busted for nothing.”

Carroll, 43, a construction manager from Mission Viejo, Calif., spent 15 hours in jail.

In the YouTube video, which had been viewed more than 180,000 by last night, the former Albany and Long Island resident and his girlfriend, Brooke Powell, are seen wearing Jets gear as they stand in a sea of San Diego fans in the Chargers’ stadium.

Carroll chants “J-E-T-S!” and pumps his arms.

About 13 seconds into the video, Carroll is shoved onto the seats by two burly San Diego cops as a Chargers fan yells, “He didn’t do anything!” and others boo and protest.

“It was completely awful,” said Powell.

Assistant Police Chief Bob Kanaski — insisting “we don’t arrest people for cheering for their teams” — said Sgt. Jeff Sterling approached Carroll after the off-duty cop sent a text message reporting a drunk causing a disturbance.

Sterling said he asked Carroll three time to “come upstairs” to talk, but he refused and made a fist.

Carroll said Sterling only asked him once and he refused to leave the stands because he didn’t want to miss the game and wasn’t misbehaving.

“The second I turned around, I got pushed down and attacked by those four officers,” he said.

“They took something from me that I don’t think ever could be replaced,” he said about missing the end of the Jets historic victory.

But Carroll is convinced there are more victories to come. “They’re going to the Super Bowl, babe!” he vowed.
