Ah ok...actually haven't heard the term before, but I kinda figured it meant something like that. Yeah, a random player I fought and beat twice on psn started sending hate mail after the first match, cussing me out and calling me a one-styler. Thought it was kinda funny actually.
I'd only say "One styler" if it was casual matches and you used one more than 4 times in a row. In serious matches I could care less. Unless its Viola. I hate Viola.
learn, then beat them with zwei, then they'll probably shut up... unless they say it's not fair because you're playing as two characters in one game XD
