Filmgasm 

A feeling of intense euphoria (often accompanied by goosebumps and a chill) that comes when experiencing an incredible cinematic moment in film or television. Filmgasms can be experienced both by an audience member or by the artist during the creative process. Filmgasms most commonly occur in audiences when viewing one of the following: the endings of "Fight Club", "Whiplash", or "The Godfather", The Battle of the Bastards from "Game of Thrones", any Kubrick film, the opening credits from "Pulp Fiction", The Charge of the Rohirrim from "The Return of the King, the final duel between Azula and Zuko in "A: TLA", and so on and so forth.

"Yo I got the biggest filmgasm working on my short yesterday."

"I watched 'Black Swan' for the first time last night, that movie gave me the biggest filmgasm ever."
