A self-reinforcing pattern of speech common in third world countries where the respondent answers every question with "yes", even when the correct answer is "no". The Yes Vortex can be almost impossible to leave as the respondent tries harder and harder to please the questioner by answering in the affirmative.
A typical yes vortex can be as follows:

Question: "You guys don't have any ice tea, do you?"
Answer: "Yes."
Question: "Do you mean, 'yes you do'; or 'no you don't'?"
Answer:" "Yes."
Question: "No I am asking if you do, or you don't."
Answer: "Yes."
