This may sound really dumb, but can I use a Liquid Nails type product to glue the vapor barrier of R-19 fiberglass batts to my subfloor?

I have a very cramped crawlspace (maybe 2-feet from bottom of joists to dirt floor) and it is taking me forever to tuck the batts in properly (vapor barrier to the subfloor), drill some screws in the joists and run twine perpendicular to the joists to hold the batts in.

Can I just slather some Liquid Nails on the subfloor and press the vapor barrier side against it? Don't know if it matters, but I live in Southern California (gets pretty chilly at night in the wintertime).

Thanks ahead for any help you may be able to offer.
