Question

What it means : what has the price of wheat to do with the size of your footprint?

yay,

ya what does it mean?

tell me when you find out

Answer 2

it means wheat comes in sizes like your shoes.

that is actually a true fact!

Answer 3

it means that the comment someone just made has absolutely nothing to do with the subject at hand, nothing to do with the conversation.

I usually have said, or heard, "What does that have to do with the price of tea in China?" in response to something that is "off-topic."

Answer 4

I would say it means you said something that was not related to the current discussion topic so someone tried to point that fact out by asking that question. Another one is "what's that got to do with the price of tea in China?"
