What is deep fart?

A fart that's released from the deepest part of your guts; often occuring in the male bathrooms in gas stations. Usually occurs after blasting out a heavy load of Chipotle's and(or) Taco Bell.

After the load of dastardly dooky is dumped, a loud, often floor vibrating, heavy bass fart is released. Can last from 2 - 10+ seconds.
