These are some great sounding words. I might try to adopt one or two!
We should really just combine everything into one big language. Or maybe not.
We already have most of these words or at least a way of describing them? E.g. Hikikomori (Japanese)" A teenager or 20-something who has withdrawn from social life, often obsessed with TV and video games."
In English, we would call this person "geek" or "nerd".
How "Gadrii Nombor Shulen Jongu" is a word? That's almost longer then the English translation
Would have some hard time pronouncing some of these
