SOS or SoS is a word often used in ytps in a poopism called "sentence mixing" when the subject speaking says something like sorry, sod, or even just sauce, but is reversed at the "ah" sound to sound like sauce. This can be done anytime someone says a word that uses the "s" sound followed by a vowel sound, or a diphthong (two vowel sounds with a transition between them).
