..are because catchier than golaloon, gohowi, gowiva or whatever gogo based attacks.
The fact that "wi" used in gowiwi or gowipe terms for wizards doesn't make sense because you always bring a bunch of wizards for ground attack. Same goes for usage of "go" for golem.
That's why someone came up with terms like "shatterred" and "cold-blooded" which only god know how they came up with the idea of usage of two golems is called shatterred and one cold-blood.
