The rivalry that's been building for a while -- at least since the pair met in the Mos Eisley cantina -- finally boiled over into an intense, and surprisingly expressive, rap battle between Groot and Hodor.

Backed by Rocket Raccoon, Bran Stark and Osha in this new video from The Warp Zone, the gentle giants of Guardians of the Galaxy and Game of Thrones throw down some mad ... not rhymes, exactly. However, they do appear mad, or at least mildly perturbed.

The lyrics are a little tough to follow, but they go something like "I am Groot, I am Groot" and "Hodor ... Hodor ... Hodor." Check it out for yourself below.
