"pico pico" is the sound/motion of "waving". Since there's no direct english translation for it, the meaning and connotation is lost in translation. Mr.Braids is probably the closest thing that we have.
Actually, although they usually call them pico-picos, this particular one called them "momiage-san". As for the pico-picos, may I suggest that we call them "wavie-wavies"? I think it's stupid enough to be yukkurispeak.
I'll back behind OhHenry since your latest comments may be pretty much a disguised attempt of breaking the rule.
After all you wouldn't like if someone went around in family friendly and said "well this yukkuris may be manipulators in disguise and something "bad" may happen to them" or "cuteness means nothing against life, and life can be quite "harsh" if you know what i mean".
Actually it's to prevent Reimu from dirtying the floor anymore. You'll recognize that in the third panel she is leaking a sort of sticky fluid out of her eyes. Her right's eyebrown in pointed down, and this in common manga style is used to show the reader that the character is angry, vengeful or similar.
Being those eyebrows this way since the first panel, we can safely assume that she is still menacing. Maybe the fluid spreading is something similar to the puffing act. After all, yukkuri's biology is still an unexplred world.
In this comic we can see the true evilness of the Deibu, who first treathens a human, then proceeds to spread her fluids all around (marking the territory as an imposition anct). Worried about the floor's status, Mister tries to stop the mucus river with the first absorbent substance he finds around.
Sadly, however, this is not enough: the Deibu still manages to attack the mister with other substances, this time not-so-fluid. It's an allegory of the persistance of the evilness in a being.
Listen HoF the thing is, well, you know how controversial yukkuris are overall. So it's usually wanted, for the sake of coexistance and such that, unless you stick to the overall scenario, it's better to not give out your disastifaction or disagreement, at least when it's as contradicting as in this situation.
You may not agree with yukkuris being microwaved and all, but as you know, commenting that is troublesome, as troublesome as people going on FF and "not agreeing" that the happy yukkuris aren't bad guys in diguise or anything like that.
There is also the whole thing of going against the wave of the stories out of your "preference" which can bother people.
As you probably saw, nobody told you anything when you went in a previous pic of this series "Well that punishment is better than what other vicious people do", but since here you are accusing the anon of not being in the right of being angry because the little ones attacked him without any rightful reason, expect people no agreeing or feeling you may be trying to do a sly or hidden anti-abuse comment.
You can say that things may had been a bit different if your start wasn't a blatlant anti-abuse troll move, people wouldn't be wary of your potential anti abuse comments and such.
And believe me, it isn't only for FF people, we have some notorious Abuse fans that bring out the same sentiment and wariness, a notorious one being AIE.
So overall the community just want's less problems and more easiness for everybody.
oh wait sorry, i mistook the stories, seriously, too much focusing on comments than in the work here. Anyway, what i explained applies to this as well, but a better example based on your comments is on "Chibi Reimu and the microwave" by the same artist.
You had a case of people not saying anything to you after an averagely ok comment and people showing disagreement and wariness when you wanted to blame the anon and say that those punished, the little ones, had the right to punish back, when they don't.
we have the people in the middle that like both abuse and ff, for variying reasons and with different side sliding proportions.
we have the people who Love Abuse works.
Some FF people act too way over their head about the morals of yukkuris forgetting that it's mainly their preference and this is all fiction, so it's all about what you like than anything.
Some Abuse people either take too seriously the highly notorious bad aspects of yukkuris, hate cute things, or plainly are tired of FF gang showing up and accusing them of being monsters, ruining their fun, etc. Specially when the ratio of "abuse fans" attacking FF works is lower than "FF fans" attacking Abuse works.
Then the people in the middle have to suck up all the drama and shit, and sometimes taking part of it and being labelled either a FF guy or a Abuse guy when they are neither.
HoF you may even realize that also danbooru has it's bits of drama and such, even without the abuse work there, yet a single mention of abuse and BOOM, shit hit the fan, so much that some people even complain about it.
That's why, for yukkuris, we need to have a more limited way of action about our comments and such. Specially in a place like here were anything related to yukkuri is uploaded be it FF or Abuse or a Cameo or anything. . .even hentai >_>. . .
>>Did he really have to go and stuff them into her eyes?
Why shouldn't he? Yukkuris get abused for no reason at all, other than enjoyment of the abuser (as it should be). More importantly, you're trying to skirt around the rules. Questioning why you should abuse yukkuris? I'm pretty sure questioning why you shouldn't abuse yukkuris and why you should let them take it easy (and not torture and kill them) would get taken as trolling.
One rule we try to adhere to is to not question why the anons are doing what they're doing. It's not people are accusing you of trolling, but its caused problems in the past so now we just don't talk about it. Because if you question why anons abuse yukkuris, it opens up family friendly pictures to question "why love your yukkuri instead of killing it".
Sounds ridiculous? Maybe. But it's happened before and has devolved into flame wars. So the easiest thing is to not talk about it. Your questions revolve around a more general premise of "why abuse?", and I don't think you'll find a simple answer right here. Post it up in the groups, and some people might respond.
