Fork Theory
The act of making stool so massive, so so gargantuin that you come to the conclusion that the toilets plumbing system is going to clog. So in fear of overflowing you take a fork ( plastic preferably for easy disposal ) and break down the feces to small managable pieces so the threat of clogging is no longer an issue.
*While staring down the toilet* "Wow, that spicey burrito was horrible idea, I may have to stoop to the fork theory!"
