Constructor's CommentsSnarkiness has been around for a long time, but there are always new ways to express your disbelief, boredom, smugness—to talk back. However, this puzzle was meant to be a fun solve, not a nasty one.
My favorite fill words in "Back Talk" are SNOG and MOOED. Also, I'm happy with the arrangement of the black squares in the grid, something I suspect most solvers don't concern themselves with (though my editors tell me otherwise).
As a fan of film noir, I was glad to be able to work in the clue [1955's "Kiss Me ___"] for DEADLY, though it got changed. Now if I can only create a puzzle using THE GREAT WHATSIT, that film's MacGuffin.
I hope you enjoyed the solve.
