Creepy guy (or gal) in the movie theater.

This reminds me of a somewhat similar movie experience that I had a few years back.

I went to see some drama/serious/whatever movie with my cousin and another friend. I can't remember what movie it was or why we saw it in the first place (because all I remember is that it blew) but this one moment made the night pretty memorable.
I remember that the main character in the movie had all these emotional/relationship problems because of his childhood, and his girlfriend was one of the only people to help him sort this stuff out.
So towards the end of the movie the main character finally breaks through his problems and he and his girlfriend finally kiss for the first time and it's implied that they are about to have sex. That was when the huge fat guy a few rows in front of us suddenly stretches his arms over his head, then claps his big paws together, starts rubbing his hands as loud as he could, and then bellows out a big "ahhhhhhhhhhhhhhhhhhhh!" Basically it seemed like he thought the movie was about to turn into a hardcore porn and he was more than excited for that.
Everyone in the theater looked over in disgust and I just started laughing so hard that I actually had to go to the lobby for a few minutes to claim down.

It was off-putting, to say the least.
