For instance, "shards" definitely does not mean "f**k." It's more like "crap" or "dammit," and a Pernese kid probably wouldn't get in trouble for saying it any more than a kid from World One would.
On the other hand, while people in World One may say "kriff" without offending anyone because it's not a real swearword in this universe, kids in Star Wars would absolutely get in trouble for saying it, and kids in Headquarters might, too.
In the middle, you've got "fork," a word from the same language as "f**k" which stands in for it because it sounds similar, but doesn't actually mean "f**k," and any kid could probably get away with saying it.
So, what I'm trying to ask is: is "flitter" more like "shards," or "fork," or "kriff"—or something else entirely? I can't tell just by reading the current page entry. Would you please expand the entry with more detail to explain it?
