If you don't actually know who Josh is... Wow. Here's the definition anyway: The friking hot drummer for Twenty One Pilots, AKA the best band on this planet. He's also Tyler's best fren for life, and no one can top their frenship (hehe, TOP their FRENship. He also dated Debby Ryan for a while, but nobody really cares about that fact anymore since Debby broke up with him (what kind of sociopath does that tf) Did I mention he was adorable and hot
