Thank you bell! Also just a note, chelsea didn't have much to do with this, me and Garu compiled it together. If anyone else Ehrik helped a bit with creating example situations for about half of the compilation.
When I was with garu and komidol making the dictionary, the example he showed for a jp fuzzy was this: ctohno 22[a] or 22d 2c. I'm not 100% sure but I think he was pointing out fake overheads and stuff...?
I think that's when we were discussing フリ, not ファジー, which is a bait or feint.
addendum:
a few of these are incorrect/mistyped.
I refuse any liability for romaji but if there are other mistakes PM me and I'll fix it for sure! I know Curbeh already scanned through this and pointed some things out to me, they're already fixed!
Can you clarify the difference between the JP and US definitions of fuzzy guard? If I had to guess, the JP definition is the same as it is for 3D fighters here, where it's a defensive technique to defend multiple options with one set of inputs. Whereas the US definition is the one commonly associated with anime fighters here: an offensive technique that forces crouching characters to assume a standing hurtbox.
Anyone who knows me knows that this is one of my nitty pet peeves. :p
I'm hesitant to post about something I'm not 100% sure on either, but there is a small distinct difference. Dippy sounds pretty spot on when he says it involves defensive techniques as well based on what I remember from the conversation that night. For them, Fuzzy is more of a game state because the defending player does have options. (Similar to how we conceived "meaty" as a situation that happens a lot in a wake up situation, "Fuzzy" is an offensive situation and common game state for a lot of fighters.)
What Garu did also explain, and spent a considerable amount of time doing so, is explaining about a term called "ファジー暴れ”, which directly means "fuzzy mash", but is different than mashing a fuzzy entirely. (And this is what is specific to melty blood.)
(I should take this time to note that 暴れ, アバレ, can mean mashing out in a dangerous situation - but is not always so; it's just any time you press a button in a disadvantageous situation, and your opponent could do something to easily defeat you. You could "mash" 2A or 2D on defense, it's not exclusive to just hitting buttons - I'm sure Jiyuna or Curbeh have a better word for just straight up mashing stupid).
Anyway, from what I gathered that night, a JP "Fuzzy Mash" is actually a state where you can use a defensive option select to defeat 2/3 offensive options after/during a "fuzzy". For America, a fuzzy is something you perform, but for JP, it's the start of a common game state (which is why they have a term for it.) While still under initial blockstun, you can input before a feint or another overhead, or a low. If they go low after trapping your hit box, your fucked (and it's easy and common for players to do, which may be why it's termed "Fuzzy Mash", it's pretty dangerous), but you can perform an input during a certain position of blockstun, such that if they feint or go for an overhead you will grab or block them. It's a defensive OS of sorts, so Dippy is kind've on track here. Sorry if some of this isn't exactly correct, like, the entire explanation was a little disorientating.

Like I said, I'm not 100% sure about this.
There really isn't a word for this in English, if anyone even knew about it in the first place. If anything, I would classify this as a smaller term for a more specific situation we would
definitely call a "Defensive OS", so I didn't worry about it too much. I neglected some of this information on purpose until I can clarify it more as well (since I knew a lot of people would be looking at this post.) Wouldn't want wrong stuff up here.
