JackRabbit2.0 showed himself to be Jackass2.0 on Thursday.

On the day after his terrible tweet, Giants cornerback Janoris Jenkins dug himself a much bigger hole even after his coach Pat Shurmur chastised him. Jenkins showed no remorse and showed he should not be allowed back in the building.

Move on, Giants. The team needs to cut ties with Jenkins ASAP.

An 11-2 team should not put up with Jenkins actions, much less a 2-11 team.

About that culture change Dave Gettleman and John Mara were so proudly proclaiming? Well, there is still much work to do.

This all started Wednesday on Twitter — where else? — when Jenkins, who calls himself JackRabbit2.0 on Twitter, criticized a fan, who criticized his play, tweeting “I can only do my job.. retard.’’

That is one vile word often used by bullies.

Many hours later Jenkins tweeted out a weak apology, saying, “My apology for the word I used earlier. Really didn’t mean no “HARM’’.’’

Then on Thursday at his locker this happened:

Pressed about his slur, Jenkins said, “Where I’m from we use all kinds of words for slang, if it offends anybody, I’m sorry. It’s a culture that I grew up in where I’m from, you understand, we use all kind of words all kind of slang. If you don’t know, it’s a hood thing. Whatever. Not calling nobody no name, pick on nobody. It’s just something we use in the hood or back at home.’’

As for the six hours it took to apologize, the cornerback dropped into zone coverage.

“Because I really didn’t see it as so bad until people like y’all started picking it up, making stories, so I just decided to apologize,’’ he said.

Giants officials did make it clear to Jenkins it was wrong.

“At the end of the day, it is just part of my culture, part of my slang that I use,’’ Jenkins said again. “I wasn’t calling nobody no name, like I said. I wasn’t picking on nobody, I wasn’t throw shade at nobody. It’s just slang that I use back at my homeboys.’’

But do you understand why that is a word that should never to used? Do you regret saying it?

“Yeah, I regret it, but at the end of the day, it’s my slang, if you take it like how you are going to take it, that’s on you,’’ Jenkins said. “I don’t mean to offend nobody. My dad always told me speak freely and own up to what you say so I always speak freely as a man.’’

Asked if he would continue to use the word, Jenkins responded, “Next question.’’

More questions about the use of the inappropriate word were asked and twice more Jenkins responded “Next question.’’

Giants public relations officials then ended the interview.

Clearly, Jenkins was given time by the Giants to apologize, but Jackrabbit went deeper down the hole. He was clueless in every way.

His “that’s on you’’ comment is hard to believe.

My question to the Giants is why even put up with such a player, who has one year to go and another $14.75 million? Make the cut. Take the cap hit.

Jenkins is 31. Time to grow up. Time to understand right from wrong and if a mistake is made, learn from it and grow and understand.

It’s actually on you, JackRabbit2.0.
