I'm building a www.clippopo.com — clip-sharing platform allowing to share moments in long videos.
People of Reddit advised that "popo" can refer to slang "cops" or related to "butt" in some languages.
When I made up that name I was referring to Limpopo river in South Africa. And there is also at least a Hippopotamus.
How are those excepted in English-speaking world? Is "popo" a real problem in "Clippopo"?
If it were my project, I would first look to the generic TLDs, and choose one that pairs nicely with the word "clip" or "clips", or something similar (but not Clippy LOL).
I would look through https://domcomp.com, filter by "gTLDs" (and maybe ccTLDs also).
Here are a few I see at a glance (not checking whois):
clip.stream
clip.link
clip.dog (with a dog mascot / logo maybe)
clip.show
clip.watch
clip.zone
clip.rip
clip.it / clips.it
clips.lol
Good luck with your project :)
Maybe people would have a problem in Jamaica or the Philippines or other minor market.
So far as "cops" are concerned, consider the word "pig" which is a slang for cops. My neighbors have pigs, there is "pig iron", the word is used plenty and unless you have some site which exists to defame the police ("Clips" of police acting badly) I think you don't have to worry about obscure slang.
