The fecal matter that gets underneath your fingernail(s) when you wipe.
"I hate it when you don't have enough toilet paper, and you end up getting cutipoo because you didn't have enough."

"I have to get a new nail clipper because I had to use it to remove some cutipoo after I went to that Mexican restaurant."

"Be sure to check for cutipoo before you return to work."
