The sound a vinyl record makes when pushed in the opposite direction to the standard playing rotation.
The DJ scratching up the vinyl flipped a zwicky then faded the next track in.

Zwicky is a lunar crater that is located on the far side of the Moon. It lies to the west of the Aitken crater, and is attached to the western rim of Vertregt crater. Attached to the northern end of Zwicky is the Heaviside crater.

This is a considerably eroded formation with an irregular rim and interior. Portions of the southern rim still survive, but the remainder has been almost completely eradicated. The satellite crater 'Zwicky N', located in the midst of the interior of Zwicky, has a relatively dark floor in comparison to the surrounding terrain.
Use your telescope to view the darker rim of Zwicky.

A sexual maneuver where you are getting blown, and as you are about to cum, pull out, stick your dick in her ear and jiz. When she screams, you quickly haul back and dick slap her across the forehead to shut her up.
"Dude, I pulled the Zwicky on a chick last night, and now she's got an ear infection
