I’ve never heard of any of those words XD
Hmmm... I know none of them.
I highly suspect whether I learned English vocab in elementary school.
None of them are real words so your knowledge of English serves you well. I just made them up for the new year! However they have meanings based kinda sort of on English maybe if you squint a bunch and add some Germanic word structure.
Youngerberry - unripe elderberry
Encaffeinjectable - the next stage of coffee and energy drinks, delivering caffeinated beverages directly into your circulatory system
Themanigans - non-binary shenanigans. Sheninagians should be available for all people.
Phlebotomatrix - woman who derives more than the usual amount of enjoyment from the removal of blood from someone else
Disentanglematon - an automated process (I think a humanoid-shaped one) which fixes all the problems you unwittingly cause for yourself
Recapitator - a rather superhuman being who specializes in the reversal of decapitations
