Hrrrrm, I mostly agree with leafgreen, but I think
polling for name-acceptance would be a terrible idea. Then again, I think when this list of "official names" goes public, it will be the laughing stock of SWF.
Hyphen Smashing: The name is very widespread and liked, so even though it's dumb, it's such an obvious game mechanic it might be best if we just left this alone. Anyway, the names "running upsmash" and "dashing upsmash" are virtually identical, and we needn't try to pick one over the other, since you can say either and it's immediately obvious what you mean; there's never been any confusion. People should be free to use whichever is more convenient; in some paragraphs you might want to stay consistent calling a run a "dash", whereas in others it may be a useful visual cue to have a sharp distinction between "running upsmash" and "dash attack" (too much "dash" can make things hard to read). There are good reasons to allow multiple equivalent names for something to exist.
(Admittedly, Running Upsmash is my preference, for fear that Dashing Upsmash would someday abbreviate to "dashush" *shudder*).
DACUS / DAHCUS / Boost-(anything): I can't believe everyone's voting for Boost Upsmash. I
never see that term in use, and it's strictly less meaningful IMO than DACUS, which is both in common circulation and actually describes what the move is / how to do it. You cancel a dash-attack into an up-smash; it's so immediately clear, once you're told the acronym.
To put things in perspective... Sonic can use a Running Upsmash, a Jump-Cancelled Running Upsmash, or a DACUS, to travel three different distances. Any of those could be legitimately called a "Boost Upsmash", especially if used out of the initial dash after a foxtrot (since you'll noticeably jerk forward into the up-smash). "Boost Usmash" is kinda awkward, but "Boost Smash" misleadingly suggests that any Smash could be used.
Also, why does DACUS need to be distinguished from DAHCUS? They're basically the same, right? (It's just that some of the opening frames of some dash attacks are able to connect before the up-smash, which conveniently gives you some time to input the up-smash from hitlag? Is that what this is?) I wouldn't have a problem calling both moves DACUS, and maybe using the acronym DAHCUS where the distinction is relevant.
Wavebouncing: It's just using a turnaround-B and a B-reverse at the same time, right? I'd just as soon encourage ppl to simply use those two "component" terms. "Wavebounce" is really widespread though, I think B-Bouncing is just as dumb. I don't think there's any real
harm from calling it a wavebounce; it just kinda sucks is all.
Kirk: It is indeed a boosted item throw. People are too used to the DAC term even though it's being improperly used over the Boost term, which admittedly has not seen any use since Melee (the term, not the technique).
Sooo.... what's wrong with the term DACIT, if that's exactly what it is? Importing terms from Melee seems of lesser importance if the Brawl community has an equally legitimate convention.
