An OKCupid date got so mad at a Queens student for not going back to his Brooklyn apartment that he stole her cellphone and hijacked her account — uploading photos of her and changing her profile to say “I’m available for threesomes,” she told The Post.

The woman, who asked to remain anonymous, said her date from hell actually began as a nice evening out near Union Square with the man she met on the popular site.

“It started pretty well,” the 22-year-old St. John’s University student said. “We talked for two weeks before we met in person.”

But after a few drinks, he pressured her to go back to his Williamsburg apartment, she said. When she declined, he became agitated — following her to the subway station, where he threw a water bottle at her, she said.

She managed to get away from the man — whom cops are now seeking — but not before he took her phone, according to her account.

“I guess he doesn’t take rejection well,” said the victim, a single mother with a 2-year-old daughter. “He was acting like a child.”

He then texted the woman’s friends, pretending to be her, she said.

“I’m all right everyone, just a little drunk but I’m home now,” he allegedly wrote.

She shared the man’s OKCupid profile pictures with police, who are investigating the incident.
