Tooth Fairy Lipstick

The residue that appears on toilet paper when lightly dabbing the toilet paper on one's butthole, usually towards the end of the wiping process after creating a bowel movement in a toilet bowl; sometimes may contain a little blood.

Maria left one square of toilet paper with some Tooth Fairy Lipstick on it for you. I've been having diarrhea today, so there is a little bit of blood from wiping so much.
