Hodor and Groot have it out in the ultimate rap battle to prove who is the true lyrical genius.
Remember that Yo app from last week? The one that did nothing but send a "Yo" to people you may or may not actually know? Well now you can send a friendly "Hodor" in much the same way! I don't know about Hodor but that makes Hodor feel very Hodor, if you ask Hodor.
