The language spoken by the lead singer of Muse, Matt Bellamy. It is often unintelligible to those who aren't familiar with his rapid, nonsensical interview responses or songs featuring notes high enough to kill dolphins (as in Micro Cuts). Notable Bellamese speech affectations include the replacement of "r" sounds with "w" sounds (ie. really -> weally), repetition of the phrase "you know", and inability to say any number besides 1984.
