Ovarian Protection Barrier. AKA Beer Belly. When a man's stomach is so enlarged that it becomes a barrier during intercourse, so much so that the belly acts as protection for the ovaries of the female.
Although he used to be quite suave and debonair in his youth, now his flirtation with my wife was a benign act due to his rotund OPB. Her ovaries were now safe from penetration.

OPB stands for Other People's Bull. This is the type of nonsense that comes out of a person's mouth that hasn't been researched or fact checked. It is very close to gossip but mostly is used in terms of political propaganda.
Why you gotta be regurgitating OPB, JaNeal? Did you even do your own research before forming an opinion? I'm not down with OPB, yeah you know me!

Other People's Bull Shit. A horrible disease affecting millions of people every day. Highly contagious, OPBS can come from family, friends, co-workers, or just people you meet in your daily life who burden others with their drama, problems and lack of responsibility.
Thanks to family and work drama, millions will suffer from OPBS this holiday season.
