It might be better as a display name than a community name. I only say that because as much as I like funny community names, they can unintentionally reduce and obfuscate community's visibility and purpose to newcomers.
If one wants it to be easily found, arguably the best community names may be either shorts or clips, followed possibly by shortvids. The display name however can be as playful as one might want, as I think frontends/apps rely on the community name when searching over the display name.
Now for the worst name, in either respect, you might make it microvlogmemes, or microvlogs, neither of which I think I've ever seen or heard anyone use anywhere. I can't even remember the last time I heard or read anyone else mention a vlog, so yeah, may be technically accurate but awful otherwise.
!ShortFormVideos is what I instantly thought. !ShortFormShares feels less formal. As an idiot, I might click thinking you are talking about the stock market, but once I saw a bunch of videos in the community it would be obvious to me what it's about
Reddit had YouTubeHaikus, which were short (often less than 15 second) videos. If you’re focused on short-form videos, then “haiku” at least expresses that.
I was of the same opinion up until the reddit API ban. Then I had a period of not having what to do while on the toilet. Leaving alone at the time video sound was not a problem and I gravitated to yt shorts for some doom scrolling whilst pooping. Now I see the appeal and usefulness since so much time people spend on the phone instead of a TV or monitor. But as usual people abuse it, long vertical videos or landscape videos cropped or resized are terrible.
