How do I characterize "disrespectful" and "unsupportive" behaviors in terms of SS?

I was rarely able to extract concrete, specific examples from teachers last year. They'd say: he needs to be supportive of his classmates or he is rude and disrespectful but when I'd ask "in what ways" or "can you give me a specific example" would receive no response.

I do have some examples of problem behaviors but those are mostly about excessive talking, interrupting, or getting up from his seat.

One thing mentioned in report was that he does not exhibit behaviors that facilitate positive teacher interactions. NP told me in conversation that refers to not thanking or seeming grateful to teachers when they "go above and beyond" for DS. What do I call that?
