Backdoor Bulimia 

Taking Laxatives regularly to exit food from your system before you gain weight. This is exactly the same as traditional Bulimia however the food passes through your anus not your mouth.
Damn Danny, yesterday I had a binge eating session and ate McDonalds, KFC, Burger King and Dominos Pizza. I'm feeling super guilty so I took a few Laxatives and am going to eject all that bad food out my anus before it sticks to my love handles. Love a bit of the old Backdoor Bulimia!

Serious eating disorder involving an obsessive need to loose weight and a distorted body image. People with this disorder binge eat and then take steps to ovoid gaining weight. Such as vomiting, excessive exercise, or fasting. Can be life-threatening from heart failure. Side effects include tooth decay and staining, inflammation of esophagus from frequent vomiting and electrolyte imbalances that cause heart failure. People with bulimia are often a normal weight to slightly overweight. Also called Bulimia Nervosa.
(Bulimia as an inner voice:)
Rue: I haven't eaten in two days. I think all just have a snack.
Bulimia: You should eat as much as possible.

Rue: After eating all of that, I feel awful.
Bulimia: You should feel awful. Go vomit it all up so you don't gain weight.

Academic Bulimia 

The process of learning or memorizing by rote, subsequently followed by the regurgitation of that knowledge onto an exam answer sheet. Just as with the serious eating disorder, this form of bulemia results in no real retention of substance.

This term is frequently applied to describe a common practice of young medical students.
I can't remember anything that I learned last night. It's like I grabbed the answer sheet, puked out all the answers and forgot everything immediately. I'd say that's academic bulimia.
