Definition

The frustrating cycle of desperately pursuing someone until they reciprocate interest, at which point your attraction mysteriously evaporates like morning dew. It's less about the person and more about the thrill of the chase.

Example Usage

Marcus is so fickle—he chased Sarah for months, and the second she said yes to a date, he suddenly wasn't interested anymore.
