I've never really understood the meaning and origin of the phrase "what have you".
You can use a pencil, a sharpie, a ballpoint, what have you.
The display room is full of stereos, TV's, and what have you.
This site says …
[…] this expression uses an archaic form of putting a question (using have you instead of do you have) as a noun clause, and what in the sense of “anything that.”
But still, this phrase does not even sound like correct English to me. Shouldn't it be "what you have" instead?
Also, since when is this phrase common, and where is it used? Is it a regional thing or generally used in all English speaking countries? Also, "Your Dictionary" says it's been first recorded in 1920, but it doesn't even say where.
