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).

Get the SoS mug.
A game, originating from family guy, wherein you and your opponent hold a mattress and ram into eachother full speed/full force. Also you have to chant UNGA BUNGA repeatedly. It can cause injuries.
