What does BYOB stand for?

Bring your own beer

BYOB is a common way to tell someone to "bring your own beer," or other alcoholic drink, to a social gathering. It is commonly sent via text messages, social media, and real-life invitations when inviting people to a get-together.

Where did BYOB come from?

BYOB dates back to at least the 1910s as a variant of the "BYOL" acronym, which stands for "bring your own liquor." It gained popularity in the 1920s (possibly due to the prohibition of alcohol sales in the Prohibition era) and has become a staple acronym for party attendees to know throughout the U.S.

How do I use BYOB?

Whenever you invite a person to a get-together, like an impromptu hang-out or birthday party, and you are not providing alcohol, you can tell the person it's a "BYOB" shindig. This lets them know that you'll be providing food, but they are on their own if they want to consume alcohol.

Typically, people ask what they can bring to contribute when invited to a get-together. This moment makes for a perfect opportunity to let them know it's BYOB. Otherwise, if you send out an electronic or real announcement, you can mention that it's a BYOB party in the details.

Variations of BYOB

While most people understand BYOB as "bring your own beer," there are other meanings that slightly differ, including "bring your own bottle" and "bring your own beverage." If you believe there may be an issue with bringing beer to the party, you may want to clarify with the host if beer and other alcohol is acceptable to bring.
