Why does Al pacino attica!attica! a lot of times???What does it mean???

Answer 1

It is from a memorable scene in the movie "Dog Day Afternoon". Pacino is in the middle of a bank robbery gone bad, and starts chanting Attica to rouse the crowd in his favor.

The Attica prison riot was a big black eye for NY state law enforcement. All deaths in the riot were found to be caused by the police called in calm the situation.

I like the line "Kiss me" to the cop better.
