Definition

Bring Your Own Crap—the party host's way of saying they're providing the venue and vibes, but you're responsible for literally everything else. It's the minimalist cousin of BYOB, extending the self-sufficiency mandate to all your personal needs. Basically, the host is offering you floor space and nothing more.

Example Usage

The camping trip is BYOC, so pack your tent, food, and entertainment—we're just providing the coordinates.
