Nerdsplain
Nerdsplaining occurs when a nerd hears a topic they love and obsess over and can't contain themselves from telling you everything they know about it. Nerdsplaining is about overwhelming excitement on a nerd's favorite subject, not about being condescending in an effort to feel superior.
I mentioned that I liked the Iron Man movie to my little brother and he couldn't help but nerdsplain the entire MCU history to me.

Nerdsplaining
(Nerd•splay•ning) Verb. To explain a subject, in excruciating detail, to someone who absolutely doesn’t give a shit. Similar to Mansplaining, except the victim is uninterested in the information being forced upon them, rather already aware of it.
My girlfriend had no interest in all of the mythological inaccuracies in Disney’s Hercules, but I couldn’t help Nerdsplaining them to her, anyway.
