Filming a take without sync sound. Often explained as "Minus Optical Strip" or the humorous "Mit-Out Sound" (supposedly said by Fritz Lang...this is some heavy Film Lore territory that is obviously just a silly rumor at this point). There are many more thoughts on what the acronym stands for, but there's no defined meaning.
