ELI5: How do poops and farts work together in the digestive system? Are they lined up in a row or can a fart overtake a poop?

The poop isn't compacted into a turd until it reaches the end of the digestive system and is ready to exit. 

It's more of a mush that doesn't completely fill your tubing, and which needs to be actively squeezed through.

Imagine some ice cream inside a drinking straw. You can blow air through it while there's still a lot stuck to the sides. To get it out, you need to squish it through. 

So, the farts do overtake the poops.
