A bowl movement that only requires one wiping of toilet paper to remove all of the poop residue from one's anus. A one wipe shit usually falls out of the anus at a high velocity and has a very solid, low liquid form; yet, it produces no splash back from the toilet bowl water.
I ate so much fiber that my poop dropped out of my anus and barely left any residue, requiring only one wipe to clean my butt hole. I wish that all of my daily shits were one wipe shits so that I could save money on toilet paper.
