native english speaker, what can you say about this one sentence?

My teacher in English was disappointed by this one sentence. It made her to write it on the board and considered as a very funny composition. Her first comment was, "what do you mean by aggrandized?" then she laughed maybe because she didn't know its meaning. secondly was she had a sarcastic comment regarding the adverb couteously. she said, "how you say that a certain person is talking courteously?"
I felt humiliated with what she had done. English speaker would mind have some comment with this one sentence. Is it wrong to use the word, 'aggrandize'.

A man aggrandized by his golden necklace courteously talks with a student.
