ELI5: The Pauli Exclusion Principle (Really bring it down)

Hello,

I wanted to learn about what the theorem means in a simpler sense than what I've been able to find online. I'd also like to know a quick summary of what the result of this principle is, like what features of atoms, technology, etc. are attributed to this principle. 

Thank you!

It's damn hard to ELI5 quantum mechanics, but here we go.

The Pauli Exclusion Principle means that two of the same kind of fermion(a particle with a half unit span) cannot be in the same place at the same time. 

This explains why electrons have such strange orbits(its not actually an orbit, but lets just assume it is for now). Electrons are all the same, and all electrons are fermions. Since electrons, under quantum mechanics, occupy an entire range of spaces at once, they form strange stack shapes around a nucleus(the middle of an atom).

This also means that atoms must be a certain distance apart to be stable, since the electron "orbits" can never intersect each other.
