nerdgassing
The venting nerds emit when some (often minor) detail of a book/movie/TV show/comic book/etc either conflicts with canon and/or handwaves through some some suspect science.
Eugene: "In the third show of the second season of Star Trek: The Next Generation, Data clearly says that the Glorithian flagship was constructed in orbit around that planet Norgar, but then in the 15th show of the sixth season, Picard said it was constructed at the Buterian space docks! How do you explain that, hmmm?"

Butch: "Stop your nerdgassing and grab me another brewski."
