yeah :p
i don't think there's a commonly used name for w-ding from the shield, mainly because people don't talk about it much. it's more common to use up B from the shield (using the same principle of jump-cancelling from the shield and quickly putting that to use). it has a lot of uses and strengthens your defensive game, but isn't necessary and generally gets ignored.
wave-shielding is a pretty uncommon term actually, since a lot people don't recognize it as a separate technique. the most common terms with "wave-" as a prefix are wave-dash (of course) and wave-shine. every so often you'll see wave-dance (like dash-dancing, but with wave-dash) or wave-shield. i've even seen wave-step (sidestep) once or twice, but nobody will understand you if you try to pass that term :p
smash terminology is kind of interesting, and you have to be careful to use it correctly. i try to avoid using "mind game" and "meta-game" because they're overused and i doubt many people really understand them.
mind games are essentially guessing games - trying to figure out the opponent when you don't know exactly what the opponent is using on you. technical skill, on the other hand, give you the options to choose from in your mind games. mind games occur rapidly in the approach, when slight changes in positioning can change everything. they are a lot easier to identify during combos and edge-guards.
however, i feel that most people have a *really* hazy impression of mind games, thinking that they are some psychic counterpart to the very physical, down-to-earth technical skill. when people say that ken has good mind games, that reflects little knowledge of what *technical skill* is, which skews the entire position. because technical skill, as i said, is the options (or firepower, if you will) for mind games, and *don't necessarily reflect technical difficulty.* a good example may be a player who always tries to launch his approach with fox's shine, vs a player who usually approaches with nair or bair. if the first player and second player are of equal skill, this doesn't imply anything about their technical skill. the guy trying to launch everything from shine, however, would be playing a much more difficult game. but they get the same results, and the simpler fox player is just as skilled technically for using an efficient approach.
the difference that sets us apart from the scrubs is, obviously, technical skill - we know vastly more than a typical casual player, not just about flashier techniques, but also in what attacks are useful, etc.
the difference that sets us apart from the tournament winners is also mostly technical skill - they've ironed out the errors that plague an intermediate player's game.
mind games aren't as significant as they're put up to be, but they do have a role. many people say that ken sort of enters their mind and plays against the player, in such a way that seems to identify mind games......
meta-game, on the other hand, has a different connotation in the pokemon world, so i just tend to say high-level play instead (as in, "high-level play has changed tremendously").
rawr, another one of my tangents :p
