Someone who Supports the FSA(Free Syrian Army) which is a terrorist organization made up of islamists, the word Rat is used as an insult, Rat meaning traitor to his country, by supporting the FSA.
Haha, look at this FSA Rat, he is so mad that his army lost the war in Syria while being supported by the west.
