I think this is joke that the invention of a new word is an example of the criticisms of the Unabomber’s manifesto which was critical of technology and the socio-political ramifications it brings? The word rizz being a word that was quickly made commonplace by the internet being the example.

Rizz may be my favourite new word in a while, the first time I read it I knew it was short of charisma, and the synonyms of charisma like charm don’t quite mean the same thing, so having a short fun way to say it is good. I’m probably a bit biased because I think I may have accidentally had a convergent evolution moment where I was also using rizz as short of charisma because I play D&D where two of your stats are Wisdom (shortened to wis) and Charisma (shortened to cha), but I didn’t like saying “ka” so I started saying rizz because it rhymes with wis.
