What is Snub in Geometry?

Question

I was trying to find out what “snub” meant in geometry after I saw it as an option in Blender, but nothing I found explained it in terms I could understand. All I know is that it’s an operation done to a polyhedron.

Also, would it be correct to refer to performing said operation as “snubbing”?
