Dane stain
A fecal discoloration, usually on the inside of underwear, cause by a disgusting, sloppy lifestyle; or an individual that conducts them self in an unself-respecting manner. Inspired by the life of Dane Ervin.
Brett had a really bad diarrhea poop the other day, and while sitting upon the throne of greatness he looked down to gaze upon the shart damage and found the most repulsive Dane stain ever.
