It's the situation that takes place when you swallow corn or eat it partially...
It´s result is the appareance of corn seeds in the toilet as you take a dump which will mostly end up in disgust by the "creator".
This happens because the human large intestine can´t absorbe cellulose (Dietary Fiber), joining it with other waste products. Which simply end up in your toilet.

It's the sweat that accumilates under big boobs
