Definition

An acronym for someone who consistently fails at things spectacularly and repeatedly—the kind of person who doesn't just miss the mark but becomes a walking monument to failure. Not quite a loser, but definitely trending that way.

Example Usage

He's become such a liaf at dating apps; he's been unmatched more times than he's had matches.
