Burning, painful rash in ass crack and/or taint (based on which way you wipe) from when you're too lazy to wipe your ass totally clean and try to still go about the daily grind.
Dude, my buttcrack is on fire! Was in a huge hurry this morning and didn't get a good wipe!

You've probably got adult diaper rash. You need to air out your asshole, man.
