A term used not only when a party thrower can not supply all of the booze at an up comming party (Bring Your Own Beer), but also used when a guy throwing a wack ass party can not get enough females to come..in this instance: (Bring your own Bitch(es)). Both ways are usually a clue to go to a different party.
Party thrower: hey man, I'm having a party tonight, unfortunately it is B.Y.O.B. in both reguards.
