Herbenflerbergerber

What does it mean? Why, we don’t know. Perhaps it means ‘to be bamboozled and flabbergasted’ or perhaps it’s slang for someone’s crotch. Or perhaps it may even be a foot infection caused by refrigerated Gouda cheese. We may never know.

Izzy: Henry, have you seen my herbenflerbergerber?
Henry: No, have you checked your toothpaste?
Izzy: Nah, that’s where I keep my chibleflibber
Henry: Well what the hell is a chibleflibber?
Izzy: Wouldn't you like to know, Crustysocks.
