A double entendre meaning a vampire or a muff diver. Famously used in a Cramps songs bearing the same name.
when the sun goes down and the moon comes up/ i turn into a teenage goo goo muck/ i cruise through the city and i roam street/ looking for something that is nice to eat

The band "The Cramps" made a song called "Goo Goo Muck"

It's a horny teenager who is ready to mingle and will take what they can get.
They might even make animal noises at girls, because they're so horny.

They roam the streets, but aim for the sheets.
A goo goo muck: "When the sun goes down and the moon goes up, I turn into a teenage goo goo muck."

Every girl on the strees: "Run for your lives!"
