M-Douche

Derived from the abbreviation MD. When a douche in pre-med tries to explain medical things they don't even understand. Often M-Douches like to pretend they are already doctors, performing half-assed surgeries in basements. M-Douches are not to be trusted and are to be reminded of their M-Douche status frequently.

Guy 1: I don't feel so well
Guy 2: You definitely have cancer
Guy 1: Shut up you M-Douche idiot
Guy 2: Yo I'm pre-med!
