Makes plans but never follows through with them. A person who is extremely overly happy. Inexplicably happy, psychotically happy.
Person 1: Hey, you want to meet me at the movies at 5:00?
Person 2: Yea
5:00 comes around and person 2 never showed.
Person 1: Man, I can't believe she pulled a brany on me!
