PBF aka Pretend Boyfriend is a convenient imaginary boyfriend who often comes in handy in many ways, such as excuse to get out of doing something, turning down a date, etc.
Occasionally Bill and I break up but it never lasts more than a few days and I know we'll be back together. So although technically we are broken up, dating anyone else feels like cheating. But Bill has to know what he's risking and that he might really lose me. That's where Carlo, my PBF (Pretend Boyfriend) comes in very handy...Bill does not not not like that Carlo is in my life!

A condition where the natural position of the facial muscles gives the appearance of being aggitated, moody, or unapproachable at all times. All basic facial gestures can be confused with a wicked case of constipation including: smiling, frowning, and even exuberance. Unlike Bitchy Resting Face (BRF), PBF can happen in men or women and affects the facial features at all times. The only real cure for PBF is to lighten up and get over yourself.
