The -1st element in the periodic table. The element contains -1 protons but has infinite mass. It is the strongest element in the universe and instantly annihilates any matter it touches. While it is a rare element, it is usually found within a star in the Jeffurious constellation, discovered by Jeffury. So far humans have only managed to contain a stable form of Jeffurium for a quadrillionth of a second.

Hopefully scientists in the future don’t use Jeffurium as a weapon of mass destruction.

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.

I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
