Oh, dude, a polygon with 1 billion sides is called a megagon. Yeah, it's like a polygon on steroids, just chilling there with all its billion sides, making all the other polygons jealous. So, if you ever need to impress someone with your geometry knowledge, just drop the word "megagon" and watch them be like, "Whoa, that's a lot of sides, man."
