"Shipoopi" is the title of a song from The Music Man, a Broadway musical written by Meredith Willson.
"Shipoopi" is also a portmanteau of the words "shit" and "poopie"; which is perhaps why children enjoy performing the "Shipoopi" song in Willson's musical.
lyrics from "Shipoopi":
Now a woman who'll kiss on a very 1st date,
Is usually a hussy,
And a woman who'll kiss on the second time out,
Is anything but fussy,
But a woman who'll wait 'till the 3rd time around,
Head in the clouds, feet on the ground,
She's the girl he's glad he's found,
She's his Shipoopi.
1. A large Satanic Nazi penis with bunny ears, a pretty awesome tweedly mustache, Gary Busey teeth and Ghandi getting a blow job from Mother Teresa. It includes another low quality penis with a small propeller so it can fly. It has an awesome set of flaming balls, and while in flight, Jesus Christ masturbates all over it.
A sex move typically performed on a female in which the male partner places an egg on the forehead of the girl before lifting his penis and dropping it onto the egg, shattering it.
