I too dislike the "zip" terminology here, for the same reason. But I
also I mislike "map" since this isn't functorial in any particular way
(I'd expect "map2" to have to do with some sort of 2-functors).

I'm agnostic on adding the function vs not, but If we're bikeshedding
for short names how about "twine"? (The problem I see with "pairwise"
is that it's ambiguous about whether values get "reused": i.e.,
matching even elements to odds[1], vs matching every element to the
next/last.)

[1] I also note without comment that this interpretation is the
inverse to what is traditionally called "zip" in the non-wellfounded
set theory community; e.g., when viewing streams (like the Thue–Morse
sequence) as a greatest solution to a system of equations.
