A male who is used by a female to temporarily fill the position of "boyfriend" until a legitimate relationship opportunity presents itself.

The stand-in bf is kept around for the amusement and satisfaction of the female, and so she doesn't get lonely.

The female will often spew phrases such as "I love you" and "I love my boyfriend", though it is and always was her intent to drop said male for one who is actually attractive.
