A specific time set to see a medical doctor. The patient usually has booked the appointment months in advance to get the first available time. A sign in sheet is at the reception desk and the receptionist is pissed because you interrupted her cell phone texting. Then the patient is handed a stack of papers to fill out and told to have a seat. After not feeling well and stressing about what may be wrong then gets to wait in the crowded, germ filled room for another 2 hrs. After the doctors appointment one may find themselves wondering why they even went and if they will receive a letter from epidemiology saying they were exposed to some contagious disease.
I went to my doctors appointment today and read old magazines in a germ filled, dirty waiting room for 2 hrs. When the medical assistant called me in I waited for another 1/2 hr in the exam room to see the doctor for 5 mins. However, I should feel lucky because I have an HMO that tells my doctors how to practice medicine.

Making plans to chillax with one of the original "doctors" (A.K.A. badass dudes) in advance, as to warrant the label "appointment." Dissimilar to simply "hanging out" with a "doctor" for the fact that it takes planning in advance to have a "doctor's appointment" with one of the doctors.
Guy 1: "Dude, I've got a doctor's appointment tomorrrow, you want to come over?"

Guy 2: "F*CK YEA"
