It’s a term used for names made up by utterly deranged and insane parents, like “Ashtrae”, or “Aeious” (pronounced Vowels) (both of which are real examples of what parents wanted to name their children pretty sure)
Tragedeih is a reference to how the names are usually utterly pretentious, stupidly long to write, and often bad
