S.O.S was a distress call that was used in MORSE CODE, long before telephones were used. To send a call for help, a telegraph operator would send " ... --- ... " It was simple and universal.
To send for help S.O.S = dot dot dot dash dash dash dot dot dot, repeatedly. If you are traped somewhere just tap S.O.S. on the wall.

Short for "Stay on Subject"
Used primarily in online classrooms; when the chatbox explodes with non-important topics such as the teacher's hair or a student's favorite aunt.
In physics class:

Dave: "Dude, my aunt is such a crazy cat person"
Mary: "Really? My uncle has a manic obsession with growing purple flowers"
Isaac: SOS guys
Teacher: Dave, Mary, and Isaac. What have I told you about talking about things not related to the subject material?
