What belongs here

Stay inside the room’s stated scope rather than adjacent off-topic dumps. Civility/anti-harassment rules apply; personal attacks get removed. Match posts to: Be kind; All NSFW content must be labeled as such.; Don't question the veracity of stories.; No punchline in the post title, but the title must describe the content. Recent samples are image-heavy; titles should explain why the media belongs here.
