isis

An Islamic terrorist group that wants the Middle East to fall into Islamic control. They fight using guerrilla warfare. Just stay away from them. They would either execute you or force you to become one of them.

ISIS attacked Syria again, they also posted more executions of civilians.

ISY

Tony- "I hooked up with another freshman last night. Is that bad?"
Joe- "Not at all man, ISY."
