How do pirates say hello?

Excuse me, I'm curious about something a bit unconventional. I came across the phrase 'How do pirates say hello?' and it piqued my interest. I'm wondering, in the context of pirate lore and culture, is there a specific greeting or phrase that pirates would use to acknowledge each other? Is it something like 'Ahoy matey!' or does it vary depending on the time period and region? I'd love to know if there's any historical basis or tradition behind this greeting, or if it's more of a modern interpretation for entertainment purposes.
