Ghoshank

A good friend. A guy around whom girls roam, An alpha male who can do anything to get a girl's contact number. Roams with girls and always choose the most out of league girl to be his crush. Good in academics but ends up destroying it just because some girl asked him to send all the notes day before the exams.

Girl:- Do you know where Ghoshank is?
Boy:- (Lowering his moral high horse) He's dead.
