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.
