B.Y.O.B.

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.

Potential Guest: fuck that dude...i got plans

B.Y.O.B is an abbreviation of bring your own booze. Usually used by the hosts of house parties, telling their guests that alcohol will not be provided.

At Janine's house party last week, she texted everyone saying 'be here for 7pm and B.Y.O.B'
