blastus

Aside from being the name of a biblical character, "blastus" is another term designating a type of fart. A very large amount of intestinal gas is expelled at considerable force. As the flattus is violently expelled through the anus, the high amplitude oscillation of the sphincter results in a great, explosive, low tone of frightful volume. The term may also be applied as a proper noun as necessary.

Grotee let loose (with a "blastus") and it shook the walls. That's why they call him Blastus.

Blastissimo 

Music that is so loud the quality decreases. A term used by acoustic musicians for when the volume of music is so great the actual sound is distorted as a result. This is similar to how screaming isn't just louder than speaking, but also raspier. Blastissimo doesn't have a set decibel level, nor is it defined by audience preference, but defined by the ability of musician and instrument to produce melodious sounds.

Play it louder
**
Louder!
**
I SAID LOUDER!

JUST FORGET ABOUT PLAYING IT RIGHT AND PLAY IT AT BLASTISSIMO!
