zips and maps

I find myself very often needing to use this function and was wondering if
there was already a way to do this using zip,maps, and folds.

zipMap [] _ = []
zipMap _ [] = []
zipMap (f:fs) (x:xs) = (f x):(zipMap fs xs)

Alternatively I can get the same affect like this:
fstOnSnd (f,x) = f x

zipMap fs xs = map fstOnSnd (zip fs xs)

Both require me to invent some new function (or use a lambda) which I am
trying to avoid. If it is unavoidable then can someone think of a better
name then zipMap?
