When a person breaks up with their significant other only to show up with a new one a short time later.
Person 1: Hey did you hear Bryan and Jamie broke up yesterday and now he is dating Andrea?

Person 2: He is such a Bran.

Person 1: Dan is Branning big time. He broke up with Laura a month ago and he is already dating Allison.
