Definition

An acronym for 'Bring Your Own Meat'—the hilarious vegetarian party equivalent of potluck where non-vegetarians are expected to supply their own protein. It's basically a carnivore's cry for help at an herbivore gathering.

Example Usage

We're hitting up Sarah's vegan dinner party tomorrow. It's BYOM, so I'm bringing a rotisserie chicken.
