What I find interesting is how the meaning of both words is... unclear. Bolide, because you have to figure it out from context (something bright in the sky/hole in the ground) and the second because it's a (science fiction-al) human (mental) state, and those are generally messy...
(Yes, I'm a fan of uncommon words - I was also amused/bemused that English, last few years, broke the mega-word barrier...)
Excuse me, but English is vastly under performing in the mega word competition in comparison to every other Germanic language.
