poop

Black hole: This poop is EXTREMELY DENSE. It also is so hard to make it plop out your ass that you end up sucking in the entire universe while you shit. Not the best. After you do a black hole poop, RUN or it'll try suck you into the toilet with it as it goes down.

Big Gaz: John the weirdest thing happened yesterday.
John: What
Big Gaz: I just shit a black hole poop, my pp got sucked in with it, I feel so naked.
