What my dad likes to call us as appose to "Dumbledoor" to reflect his nerdiness.
Or an annoying name that that one kid in your class just learned and now won't stop using.
Or as a full name ~DUPLEDOOR MC STINKLETOES~
*Don't really even know what it came from because my dad just started using it one day*

Literally everyone, ever. Including the writer of this definition.
