Poo Bum 

After taking a massive shit and wiping, Poo Bum is the last bit of shit that won't go away. Usually noticed after getting up and walking around for a while leaving your ass cheeks moist. Cured with a Wipe Down

Oh man, my Poo Bum left a shit stain in my boxers.

Do you have a little Poo Bum Robby?
