B.O.B. can be applied to anyone with a first name beginning with the letter "B" who is black out drunk. This person is no longer simply buzzed or a little wasted but full on hammered and hopefully out of control. They will most certainly have a glazed over look in their eyes and will lose motor function but definitely will not stop drinking, chain smoking, dancing and trying to get laid from people who may or may not be hot. At this point, they are too hammered to remember anything so they will be free of the shame which normally governs their lives making these drunken antics quite amusing to their cohorts.
