When you don't know the words to a song, the word schmoo is used to replace the words that are not known. It can be abbreviated to 'sch' or add 'ey' to the end to give it more versatility.
The YMCA song: "YMCA! Sch sch sch sch schmoo schmoo. YMCA-A!

The Bubba Sparx song I found you, Ms. New Booty: "I found you, Ms. New Schmooey!"

A balloon like toy that became a craze in the '50's. Schmoo's appeared in the cartoon series "Lil'Abner." They invaded the town.
I know this is ancient history to you, but a schmoo was a great toy, and fad. And if you don't care, I say screw you, schmoo.

Someone who is a massive party pooper that doesn't really care about others, just themself. They also think that they are a genius, and will occasionally say things like "hasta la pasta" or when asked what's up, they say "the sky". They also can't take a hint to save their life. There is a high possibility that they have worn a fedora at least once in their life.
