Lol, are you serious? "Real monkey hateful"? He's saying "We'll not be hateful", referring to the episode. It's the one where they get a therapist because they keep having violent conflicts with each other on stage. The therapist takes advantage of them and claims himself as a part of Dethklok, and bribes them with Banana Stickers. "Real bloody hateful" is a reference to what the therapist is doing, and "we'll not be hateful" is a reference to them being obedient for banana stickers.
