Power Morning Fart
The extremely powerful and loud fart one generates after waking up in the morning. It can happen either in bed, or while taking the morning pee. When it happens its extremely satisfying and personally amusing and is usually followed with a "WHOA!". Normally there is no smell, only hang time. When done in while taking a shit you can see the toilet water part or ripple.
Dude Matt, I ripped a power morning fart so powerful that it blew out my house windows and made the cat shit it's pants!
