butt cheese 

The accumulation of feces, toilet paper, lint, and other detritus in the area between the buttocks. With time and mechanical action, assuming the appropriate binding elements are present, butt cheese takes a granular form which is known as dingleberries. Uncontrolled, butt cheese can progress beyond dingleberries to dinglebombs or in the vernacular "butt grapes"

"I need to go re-wipe, or my butt cheese will be a nice crop of dingleberries by supper"
