It means Save Our Ship, but it can be used for any way of distress. Many people think that it stands for Save Our Souls but in reality it was created by men that were out stranded at sea, also those who thought it stood for Save Our Souls are a bunch of wankers.

Get the SOSmug. 
Get the sosmug. Though originally meaning 'Save our Ship'. It can also be used as 'Save our Souls'. Used in situations of much panic and much sad and much desperation. Used to make sure that two souls are saved. We can say save our souls when in much bad situation. It can also be used by two people praying to god or any greater being and asking that being to save their souls. They would be like 'Save our SOULS!'
