My bands name is Blood Painted Morgue, but if i had a crappy punk/grind project by my self just to make fun of music, i would call it "growler" and it would suck.
If i would have another serious band then its name would either be Deathwind or Deathstorm, and if such a thing would not exist already, Hellstorm. Oh and Hellwind would kick a load of fat butt as well.
I think that band names like Destruction or Slayer or Annihilator or Death Angel or Dark Angel are generic and crappy names. A name needs to be original just a little bit.
