Top definition
A word that can be substituted for pretty much any other noun in the English language. Ususally used in an insulting manner, but sometimes used to show the superior quality of an object and/or concept.

In layman's terms, the meaning changes constantly. Moldu is what you want it to be. Its a very flexible word.

3. Oh, don't be all moldu, its a party!
4. Eragon is a fucking moldu.
