Octogram
The shape you get when you throw a hexagon into a blender and forget to put the lid on.
My geometry homework had an octogram on it. I threw it in the trash. It didn't stop being a shape.
I asked my teacher if an octogram is a real thing. She said yes. Then she said it's a real pain.
My friend said he saw an octogram in the sky. I said he was high. He said he was enlightened.
