This guy’s a real ass.

NYPD cops are looking for a thug who goes by the street name “El Burro” — the Donkey — for shooting a woman multiple times after she rejected his handsy advances at an underground dance party in the Bronx early Monday, according to police sources.

The 20-year-old woman said she was partying with pals in the basement of a building on 165th Street around midnight when a guy she knew as “El Burro” offered her a drink and then started dancing with her.

But then he went too far, and grabbed her buttocks.

She pushed him off and left the dance floor for the bathroom, sources said.

Video released by the NYPD shows the suspect boogieing down on a crowded dance floor in a white cap and white jacket.

While freshening up, the victim heard several loud bangs, then realized that she had been shot several times in the legs, arms and hand.

Other partiers could be heard saying that “El Burro messed up” — blaming him for the shooting, sources said.

Her friends rushed her to Bronx Care Hospital just before 4 a.m., where she was treated for wounds to her left hand, right elbow, right knee and left leg, according to sources.

“El Burro” is described as a dark-skinned Hispanic man from Venezuela in his mid-20s to early 30s, 6-foot-3, and about 190 pounds.
