Imagine this kid in high school telling you he's going off to fight ISIS for the YPG. You laugh in his face, and rightly so - this four-eyes isn't going to Syria to take up arms. Years later, you log on to this Twitter thing everyone is talking about and some guy named PissPigGrandad is all over your feed... and it's the weird kid from AP history who wouldn't stop showing off his keffiyah and correcting everyone who called it a scarf.
