An unhinged man was busted after he allegedly threatened to "massacre" partygoers outside an Astoria nightclub.

Ismael Piedrahita, 26, was raising a ruckus in front of the club on 57th Street near 32nd Avenue early Sunday when a security officer approached him, sources said.

"I have a gun in the car. I will massacre you all," cops allegedly heard Piedrahita shout.

He clashed with officers and yelled, "Get away from my car," slamming his door on a cop, according to court papers.
