cinemadultery 

The act of watching a movie with someone other than one's spouse or significant other, esp. after agreeing to watch that movie together.

Going to see Slumdog Millionaire with his coworkers last night after he promised we'd see it together was an act of cinemadultery! He's so in the doghouse!
