Occurring mostly with women, It's a phenomenon that occurs due to having a fat stomach and weak and flabby obliques muscles, often leading to a sagging appearance on the sides, but a upward bridging point under the navel, creating a "butt" appearance. Similar to a bumstache. The size of the gut butt varies based on the circumference of the individual.

It is not uncommon for those suffering from gut butt to have a stomach than their actual butt. Gut butt may be the result of an uncontrolled fupa, but it does not have to be in origin.
