nerdcheck
Coined on episode 33 of the Bloody Gun Club podcast, to nerdcheck is to correct someone with (overly) technical details, especially when it has no real effect on the conversation or situation. The correction usually starts with, "actually" or "technically." It usually makes you want to yell, "WHATEVER!" in their face.
"Person1: The song is 3 minutes long."

"Person1: Don't ever nerdcheck me again."
"Person2: Technically, 3 minutes and 2 seconds."
