A male character in a movie telling a female character to calm down because she merely stated a concern or opinion, but the tone and delivery is as if she's raising her voice, weeping and screaming. The term is a portmanteau of "mansplaining" and "gaslighting". It was originally coined in the "screenwriting" subreddit as a description for one type of bad screenwriting.
When the man in that movie was telling the female protagonist to just calm the f*** down simply because she pointed out that he shouldn't light up a cigarette in a room full of high explosives, he was clearly gasplaining her.
