When someone does a split then suddenly shits them-self.
My friend was showing me there gymnastic moves when they took a banana-split shit
When you take a shit and the first log feels like a cheese grater or nails scraping against the insides of your asshole while it's coming out. All you can do is wait through the pain and misery.
I just got done taking the worst Asshole Splitting Shit of my life...
When you have a last minute, unavoidable need to quickly poop, before dashing out somewhere important.
My lunch break is nearly over, but I need to sit, shit & split.
