1.
A period lasting at least an hour of listening to awesome music by the most fantastic band ever made (MUSE) whilst reading and looking at anything associated with them.
Guy: 'Duuude why were you liking so many MUSE groups on facebook? And continually saying how underrated 'Sing for Absolution' was?'
Girl: 'Sorry man, I went on a bit of a Muse-athon - but hey, at least it's not some sucky twelve year old girl' (see Justin Bieber)
