I had oral *** during Wall-E. There wasn't anyone else in the theater though; I don't think. At least your movie makes sense. You'll see weirder things as you get older.
Would have thrown my stuff as well. Spending some bucks to see a movie, only to turn out that you can't enjoy it when you have some dude screaming out loud "AHH... Yesssss baby" 24/7. It isn't that hard to find a private place.
aaah the cinema..had some nice moments in there.
My gf actually tried to get me to watch that movie a few weeks ago but I refused. Boring *** and the city crap.
OT: You sure had an interesting evening xD wish I was there to see the chaos
A couple of my friends in college once said they had a similar experience, that being they were near a guy getting head in a theatre and it pissed them off. Normally you'd place yourself in the far corner so others aren't as aware, but obviously this couple didn't do that. The guy having no self control only made it more obvious lol.
