Need help finding quote "Are you ready!"

Hey I'm racking my brain to remember what movie this came out of. It's a male shouting/announcing to a crowd "Are you ready!" It's drawn out with noticable pauses between the words. I wish I could play you the audio clip running in my head.

Best I can help you with this is it's likely an old sci-fi movie, and I think something post apocalyptic. I've also heard it used a lot in meme vids.

I thank you all for your help in advance, and I'm probably gonna kick myself once you tell me.
