I think its nice having words for very specific situations, every language has them and it gives more spice to it. Now yes, these neologisms are all made up words by one guy, but as Thor said:

"All words are made up"

If enough people use them, they become regular words and thats kinda neat.

I love how everyone is a Psychology expert nowadays and can pull new emotions and diagnoses straight from the studies of the university of "because i say so"
