A habit of speech and conversation whereby a questioner asks a very unspecific question of a questionee, or series of such questions, leading up to the actual question which the questioner would like the questionee to answer. A waste of conversational bandwidth, be it spoken or digital.
"Can I ask you a question?"
"You just did."
"Yes, but only one, and you already used it up."
Metaquestions are questions about other questions. Which are asked in response or leading up to other questions.
They are almost always dependent on the other question.
Can I ask you a question? *
- You just did.
Stop answering each question with another question.
- Why shouldn't I answer each question with another question? *
* This question is a metaquestion.
