Someone's ass when laying on their side with shit still in their butt crack from their last dump.
Dude, it was so gross Jon totally gave me the dirtiest chocolate smile yesterday!
While taking a dump you feel the stool come out of your butt but nothing hits the toilet water. Upon wiping you realize that nothing hit the toilet because it's all still on your ass crack.
Man yesterday I had the worst shit ever. There was poo all over the toilet due to my losing streak!
