When a program takes a moment out of its busy day to have a look at its own metadata, that's called reflection. I suppose the word indicates a sense of the program looking at itself in a mirror to check whether its lipstick is on straight, or something. But, wouldn't introspection be more spot on?

Hmmm... It is reflecting on itself.
Yikes. I'll stick with System.Reflection.
