Shift-x

shift-x, adj. ("shift ex") 1. in the Marvel Super Heroes RPG, one of 18 levels of character ability ranking, representing a range from 126 to 175. 2. in gamer lingo, really good but not the best. Ex: Her looks are shift-x, but my ex-girlfriend's hotter. See also monstrous. [GJ1]

Addendum: Gamers use the MSH terms shift-x and monstrous facetiously, since the whole "descriptive" ability system in MSH was pretty damn stupid. [EDE]
