A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Given that a headline is a thing that is designed to make you want to read more, literally all of them could be called clickbait.
But really it's the more egregious ones like, "You'll Never Believe...", "This Weird Trick..." or "Make Sure you Watch Until the End" that truly deserve the title.
Not much bait but you got a few clicks.
This post is not a clickbait
