I really like a lot of the Japanese move names. Iconoclasm. Northern Lights Bomb. Burning Hammer. Chimera Suplex is pretty brilliant (it's a combination of Tiger, Dragon and German suplexes) Diamondhead.  
  
I dunno about Emerald Frosion. If it's meant to be Emerald Fusion, it's pretty great. Emerald Erosion? Lame.  
  
Make your own Japanese move! 
  
*) Optional: Pick a color! 
  
A) Pick one or more from the following: 
Phoenix/Tiger/Dragon/Fire/Thunder/Burning 
  
B)Pick one of the following: 
Slam/Driver/Bomb/Kick/Splash 
  
*)Optional: Pick the date you first modified it to make it more deadlier! 
  
  
EDIT: Joey Styles, intentionally or unintentionally mispronounced 'rolling elbow' as 'roaring elbow'. 
  
I always thought 'roaring elbow' sounded cool.  
  
Yeah, Styles Clash is a pretty lame name for a very cool move. I also hated the name of Low Ki's twisting gamengiri 'The Matrix', though I think I only heard it referred to as such once. 
  
West Coast Pop is a pretty horrible name, though he can't do it like he used to. (back in the WCW days, with other cruisers, they never touched the ground!) 
  
The Sicilian Slice was a pretty cool move (Rocker Dropper from the second rope by Guido) lame name.  
  
Lastly, I like the 'Edge-o-matic', (Edge's move, essentially an inverted X-factor), though it's not a finisher, but it's a stupid name that means nothing. Only thing I can think of is that Nova had a pretty lame move called the 'Sledge-o-matic.'
