When a girl and or woman or homosexual male feels a strong connection to Justin beiber and thinks they will be married. Also know to be a term for girls who are hipnotized by Justin and feel that they should compare ever guy to him and be picky. Or when a bitch who is fat,smelly,and or ignorant believes Justin beiber loves them and feels the right to hate on non homosexual guys.
