Supposedly rediscovered in the Fall of 2011, the "Dirty Shipoopi" is an act performed during sexual intercourse, where a person defecates into his/her partners anus or vagina and uses the feces as a type of lubrication.
The word Shipoopi is a title of a song from the 1957 musical The Music Man by Meredith Wilson.
Several historians believe that the word was created by Meredith Wilson after performing this sexual act. After the word was created, it is said that she then created the song.
