A stupid person; a brainless person; just a word used to insult someone; a word to insult someone but being fun about it. ALWAYS USED AT THE END OF THE SENTENCE (it's a non written rule)

All UD Dumbass Editors. They’re all stupid and made up off e-girl 14 year olds. They whine and cry and reject good definitions. If a UD editor is reading this, fuck you. UD Editors are the equivalent of Discord Mods.
UD Dumbass Editors when they see this: Waaaaaaaaaaaa!!!!!!! This guy is calling me a dumbass idiot!!!!!!!! Waaaaaaa!!!!!!!
