Nerd Out 

A Nerd Out is when you deep dive a subject beyond normal reason, or common knowledge.

Often this is in an attempt to learn or simply to try to understand the topic at its roots.

Ex: After getting into podcasts, I would nerd out on the subject for days and I found out they used to be called audioblogs, but the name changed after the advent of the iPod.

Nerd Out 

To passionately study a topic beyond reason or common knowledge. You can nerd out about Shoes, Mars, or Zelda and know facts that even the most dedicated fan doesn’t know.

I can’t help but Nerd Out on marvel movies; go back and read related comic book arcs, spend hours on Wikipedia and watch every morsel of behind the scenes and making of content.
