When you behave and/or act crazy & irrational intentionally; all in retaliation of someone acting crazy & irrational towards you.
This is done so that you catch them off-guard and give them a taste of their own medicine.
Guy: "That bitch won't leave me alone... she keeps trying to add all my friends!"
Friend: "You have to get reverse crazy on that bitch and have all your friends ADD HER!"
