A "teaser" aims to exploit the "curiosity gap", providing just enough information to make readers of news websites curious, but not enough to satisfy their curiosity without clicking through to the linked content. Clickbait headlines often add an element of dishonesty, using enticements that do not accurately reflect the content being delivered. The "-bait" suffix makes an analogy with fishing, where a hook is disguised by an enticement (bait), presenting the impression to the fish that it is a desirable thing to swallow.
