When you have a fart that is so nasty that you have to go to the bathroom and wipe your ass because it feels like more than just air came out.
(Person1 shits his pants)
Person2: Ew that was fucking nasty dude.

Person1: Sorry, I think I need to take a courtesy wipe. I’ll be back.
(Person1 sprints to the bathroom)

Get the Courtesy Wipe mug.
When you are done wiping your ass after taking a shit and you're not sure if you wiped everything away, the decision for a courtesy wipe has to be made. This is done as a courtesy to other people that might have to deal with your stank ass from not wiping enough.
Adam: "What is that smell?"
Mike: "I don't know. I don't smell anything."
Adam: "Did you just take a shit?"
Mike: "Yes I did."
Adam: "Did you consider a courtesy wipe?"
Mike: "What is that?"
Adam: "At least we know what that smell is now"
