@youronlyone I think you might be slightly misremembering things.
* Distro: Ubuntu, Debian, Arch, etc.
* Flavor: Kubuntu, Xubuntu, Lubuntu (for Ubuntu); Mint's various "Editions", etc.
* DE: Gnome, KDE, LDE, etc.
And the other major one you couldn't recall is likely the package manager (apt, rpm, pacman, etc.), which you might have mixed up a bit with your definition of Distro
