He has called himself “the world’s most eligible bachelor” on Twitter — and just days before his bust bragged, “I’m the most successful Albanian to ever walk the face of this Earth.”

But Martin Shkreli’s most impressive achievement could well be the unanimous rage he inspires from everyone from price-gouged AIDS patients to rappers to federal prosecutors.

“KARMAS A BITCH,” actress Debra Messing tweeted Thursday, summing up reaction to the news that the sleazeball businessman is now facing up to 20 years behind bars for an alleged Ponzi scheme.

The 32-year-old hedge funder and entrepreneur, who was raised in Sheepshead Bay, Brooklyn, by Albanian immigrants, remains most notorious for hiking the price of a lifesaving cancer and AIDS drug, Daraprim, jacking up the cost per pill from $13.50 to $750.

Two months later, in September, the baby-faced braggart was revealed as the buyer of a one-of-a-kind album by the Wu-Tang Clan. He paid $2 million for the album, “Once Upon a Time in Shaolin” — on the condition that no one else can ever listen to it without his OK.

“I’m not going to play it for no reason,” he bragged to the music news site HipHopDX in an interview that ran Dec. 9, a week before his fraud bust.

“If Taylor Swift wants to come over and suck my d- -k, I’ll play it for her,” he said, laughing.

Following the Daraprim outrage, the Wu-Tang Clan distanced itself from Shkreli, with member RZA reportedly saying it had given part of the proceeds to charity.

Shkreli also fancies himself an aspiring rapper.

“All these guys rap about is money, and I have a lot to say . . . I make money,” he boasted.

“That’s what I do. That’s why I can f- -king afford a f- -king $2 million album.

“What do you think I do, make cookies? No, motherf- -ker. I sell drugs,” he added with a laugh.

The Wu-Tang album isn’t his only pathetic reach for the mantle of fame.

Last year, he boasted of owning another celebrity trophy — Kurt Cobain’s credit card.

“Wonder if it still works,” he tweeted with a photo of the Nirvana frontman’s card.

Shkreli said his Murray Hill apartment boasts furnishings even blingier than the album, which came in a specially designed box.

“I’m staring at a Picasso in my living room right now that’s no different from the Wu-Tang box except it’s about 20 times more expensive. It is what it is,” he sneered in the HipHopDX interview.

And there are even more reasons to love to hate Shkreli.

On his OKCupid page, he boasted that he’s really good at “Making drugs that save people’s lives. Hanging out on the internet. Generating shareholder value. Eye rolls.”
