Can anyone find this sample in Side by Side?

If you listen closely to side by side you can hear what sounds to me like the squeaking of shoes on a basketball court, and what could be a basketball hitting the court. I'm thinking this could be a sample from a song in a basketball movie or something. Also, you can hear some vocals in the background that play in time with the melody every 4 bars so I think they could be a part of the sample as well, and not Bladee's or Thaiboy's voice. Does anyone have any idea where this sample might be from?

Clearest example of what I mean, I tried using AI vocal separation but it sounded like shit
