A word used to describe any work by manga artist Go Nagai, meaning that it's cool and overall amazing. Comes from the title of one of his popular works "Mazinger Z". Could also be used to describe dynamic or abnormally spiky sideburns, as most of Go Nagai's characters had them.
"Getter Robo, Devilman and Cutey Honey are all Amazinger."
