Everything is "made up" if you stretch the definition far enough; people are "made up" of cells, but does that have anything to do with the point she was making?
No it doesn't.
"made up" is being used completly differently there.
Not sure why you even brought that up.
The "offical lexicon" (which there is no one single source, closest thing you have is a dictonary, which no one would bother to check) would not include many words we use here, nor would it include names of people we all know for the most part.
