Masturbating while listening to music from the band Mastodon.
usually in correlation with the tempo of the song,guitar parts,or drums.
due to this fact,you often must change speeds and rhythm rapidly,making for a better experience.
Drew:DUDE! i just Mastobated to all of Leviathan!

Micky:No way! how big was your Iron Tusk?

Drew:Huge! it was awesome,its like i have a Hand of Stone!

-OR-

Mickey: I know just how to wake up my Sleeping Giant,ill just pop in Blood Mountain and...The Wolf is Loose!

Grandparents: Mastobation sure keeps our Hearts Alive!

so on and so forth...
