What Matt Bellamy does to let loose his raging lust for his guitars during shows (and perhaps after shows as well... no one can confirm it, yet). It involves a humping motion toward whatever lucky instrument he happens to be holding, often during a passionate riff or lyric.
1. Holy hell, Matt's guitar fuck in the last song gave me multiple musegasms!

2. Did you see Bells guitar fucking the Gliteratti? Keytar's getting more jealous by the second.
