§§§A secret to boom operating is to:
"...[Y]ell out “Stand by for speed,” in [your] most professional voice, to let people know that [you are] not ready, and speed has not been called."
It's a secret. Don't tell anyone. Although personally I'm a fan of saying "Flying in!" and then proceeding safely and apace with whatever you were doing when someone calls for something on set. Just don't say "Wait". Drives everyone nuts.
