Definition

To yearn for something or someone with an intensity that borders on melodramatic longing. It's desire elevated to an art form, the kind of wanting that makes you stare wistfully out windows and sigh dramatically. Originally more poetic, now applicable to everything from unrequited crushes to discontinued snack foods.

Example Usage

I'm still pining for those limited-edition Oreos they discontinued three years ago.
