movie adultery 

To betray someone by seeing a film you had promised to see with them first. Essentially, the breaking of a promise to participate in a shared motion picture experience by enjoying it all by yourself.

I promised Mark I was going to see Minority Report with him, but I succumbed to the temptations of movie adultery. Curse its siren's song.

To betray someone by seeing a film with one person when you shud have shared the motion picture experience with someone else.

I had to go see CHICAGO a second time, this time with Terri, even tho I had seen it with Nancii; otherwise the movie adultery would come out.
