I just read a question here at ELU where a certain user, I'll call him A, disagreed with the premise in the question. He wrote a comment to disagree with the premise, and wrote that actually, such-and-so grammar thing is not necessarily disallowed. OP requested an example that would be kosher. A gave a smartass response, telling OP to study the difference between certain fields of study.
I need an alternative way of expressing the idea of the smartass response, that's not vulgar. It doesn't have to be a single word and it's okay to rewrite the sentence.
