What are the people in the theater saying???

You know how whenever they finish talking about a film, and they cut to the angry theater throwing popcorn at the screen? Yah. What do you think they are yelling?

Me and my older bro have agreed that they are yelling "Arrrghghg Seinfield!"

I have El Sonoma del Torra de Fiero Syndrome. Be happy you don't. Trust me.
