: : can anybody help with the meaning of this
: It was discussed just last week. Look in this :
One of the posters in the original thread mentioned above, guessed at a possible U.S. baseball connection for this phrase. But I don't think there is such a connection. A baseball hit into the air by the batter is called a "fly ball" but it's rarely (if ever) referred to as "flying". Fielders try to catch such a ball "on the fly", but not "while it is flying" or even "while it flies".
I should also mention that I've never heard either variation of this phrase. I'm from the Northeastern U.S.
